Everything was written on the back of the book.

Hmm.. I'm not sure. I found both to be predictable.
I figured Snape would be a good guy in the first book once it was revealed that he was trying to counter whatever was being done to Harry's broom during the Quiddich game.
I figured Harry and Ginny would be together when it was said she had a huge crush on him, again in the first book.
I also figured Ron and Hermione would be together in the first book, I forget why.

I knew a lot about Twilight before I began reading it, but that's because it was 2009 and there were spoilers everywhere.

Foreshadow abuse, Rowling.

What do you mean foreshadow abuse?

twilight

Well, Twilight was pretty predictable because as Gred and Forge said, she slapped "Edward is a vampire" on the cover of the first book, I forget about the other two, then "Edward and Bella get married and have a baby" on the last one. JK Rowling tends to let you read the books and figure out the plots and subplots.
Plus, I don't think Harry Potter was predictable. I did guess Snape would be good and the Ron/Hermione thing, I also guessed Voldemort would be defeated and Harry would come close to death but I guess the last one was just everyone's guess, and I mean everyone had their own theory. I don't think she "foreshadows" at all, I just think she uses those things called hints in her books.

both really.

Harry Potter was very unpredictable, who would ever had guessed about the Horcruxes and Lily/Snape and stuff? While in Twilight....I never doubted for one second she would chose Edward over Jacob, be turned into a vampire, and live Happily Ever After *vomit*

TBH

Easily.

There were only a couple things that I knew before the end of the series: Severus was a good guy, he was in love with Lily, and Ron/Hermione.

Come on no one expected Crabe or Fred to die Rowlings always throwing twists in.

It was a really stupid decision to put "Edward's a vampire" at the back of the Twilight book. I mean, they just gave almost everything away, making most of the book pointless to read.
Anyways, yeah in it's own way HP was predictable, but really hands down Twilight was the most predictable book I've ever read...

the series wasnt about finding out Edward's secret. i knew harry was a wizard before he knew it because i read the back of the book and i looked at the cover. HP isnt about harry finding out he was a wizard

^No, that's not what the series' were about. But JK didn't spend half the book building up the "mystery" of what Harry was. Officially Harry finds out around chapter two. In Twilight, Bella officially finds out around chapter nine, after snooping for clues and coming up with theories about what he was.

if Bella found out earlier, i could imagine people complaining that it was too rushed and its not realistic for her to find out so soon

Not if since put the "big secret" on the back of the book and had Jacob tell her the story on the beach.

i actually knew who was a vamp caus it was in the bak of the book
fail

It was really predictable, mostly because of the subject.
Edward is a vampire, Bella a human, they fall in love.
There are also villains, who ALL try to kill Bella,
the Cullens kill them and here's one happy ending.

While HP was totally different.
I didn't know Snape was the good guy,
I didn't know a thing about the Horcruxes,
I didn't know so may people were about to die.
I didn't know the reason why Harry survived that night.

So many things JKRowling surprised me with :D

I guessed right about Snape, but only because I read the books so often and could spot little hidden hints like that. There were SO many things I would NEVER have guessed. And there was just so much more to speculate about in the first place than in Twilight.

I mean that she foreshadowed a lot, and so often, some results were obvious in the end. Less foreshadowing would have made is less predictable.

I didn't find Harry Potter that predictable actually. It's understandable why some people would find it predictable, but I personally didn't. I suspected (in Deathly Hallows) that at least one of the 6 that went to the Ministry of Magic in the 5th book would've died (Luna, Ron, Harry, Neville, Ginny, Hermione), but to no avail. Among other things, obviously.

I also found the Deaths in the 7th book to be extremely random - as if she picked them out of a hat or something. The only predictable death, in my opinion, was Voldemort. And possibly Snape. I mean Hedwig? SERIOUSLY?! I predicted Sirius to make a comeback, I always believed him to be alive behind that veil. Basically, what I'm saying is that Deathly Hallows was extremely unpredictable, I honestly did not know what was going to happen.

But then again, I only started reading Harry Potter when the Goblet of Fire film was released, and I just read it. Like, I didn't predict anything, if that makes sense. The only predictions I made were for Deathly Hallows, all of which were untrue. So..

Honestly, I was on the fence about Snape being a good/bad guy. Even though Dumbledore trusted him, if Harry didn't, I wasn't sure which side he was on (even though he loved Lily). Also, there were many hints that a major character in the final book would die, and there were many that speculated it was going to be Harry. I never saw all the random deaths that were going to happen in Deathly Hallows (Fred!).

The only thing in Twilight that wasn't totally predictable was Jacob printing on Renesmee (eww). I honestly thought he would end up with Leah. They have the same upbringing and even though they fight, she was loyal to him and his pack. I never thought Jacob would go all 'omg, my soul mate!' to Nessie, especially since he 'thought' he was in love with Bella. But then again, if Quill imprinted on a 2 year old, I wasn't surprised that Jacob did the same to a newborn.

Everyone knew what was going to happen in Twilight.
I never guessed what was going to happen in HP. To be fair, it could be because I'm young and haven't read enough books to see twists coming, but I still feel Twilight was a lot more predictable.

There were a lot of twists and turns in the Harry Potter series, just a few been.... Voldy sticking out of the back of Quirrels head (did anyone really figure that one out?). The Basilisk killing moaning myrtle, the first horcrux made an appearance in Chamber of Secrets, Sirius Black been Harrys Godfather and fathers best friend, Pettigrew been Rons pet rat, Sirius not actually wanting to kill Harry. Voldermorts elaborate plan to get Harry alone through the Twi-Wizard tournament, Cedrics death was a big surprise. Dementors attacking Harry in Order of the Pheonix, his expulsion, Mrs Fig been a squib, Bill and Fleurs relationship, Dumbledores death :0( Hedwig :0( the ambush as Harry left 4 Privet Drive, Moody's Death.....no everyones death including Harry! I could go on and on lol Where as Twilight is a fairytale, girl meets vampire boy and becomes a vampire. Jake and Renesmee were a shock though.

I would say Twilight.
There's no way in hell i will predicted Mad-Eye will died (he's the best Auror!), also Sirius (sobs), Fred, Tonks, Remus, etc..

becuase once she said she wanted to be a vampire u just knew it would happen

Twilight was like an average fairy tale - the sort that always has a beautiful princess, and her charming prince, and after some average issues, they end up together and live happily ever after.

average issues?

so ironic that when harry potter is winning, even you don't want to vote

i didn't vote because i made this pick. i don't know, so i asked other people

i knew everyone was going to pick Twilight, but that doesn't matter. I want to read the comments

i mean, DUH, shes going to live, DUH,EVERYONES going to live. i mean, DUH, shes gonna be a vampire!

I always knew they were gonna have their happily ever after. Nothing ever made me think they would not end up perfectly happy and winning everything.
