His constant flashbacks annoy me. He's fine in flashforwards though

Love Jack, love Matthew, so why is he annoying??

I agree, too much Jack! And he just needs to learn to relax, hang out with Hurley a little!

he just irritates me, he's always trying to save everything : 'I'm going to fix you'

Kate has the same flashbacks all the time and she doesn't have a good on-island story...

He's so self-righteous! And he never listens.

I don't wish him dead, but the amount of time I have to spend with him is completely out of proportion to the amount he is interesting.

She was really interesting back in the first season, but she has been boring throughout seasons 2 and 3. She was especially annoying towards the end of season 3.

Somebody picked Hurley? :(
I didn't really dislike Juliet since the season finale but I still find her really annoying.

I know! Hurley.. :( My brother thinks he's annoying as well and everytime he says that I slap him...

How can anyone find Hurley annoying? I also can't believe that someone picked Vincent the dog as the most annoying.

Is he always trying to save something? Of course, Jack is A HERO...¬¬ By the way, Juliet irritates me...

Someone needs to put her out of ALL of are misery. (very lame character)

her flash backs are so boring that it wreaks the episode for me :'(

something about her is so annoying
I decided that it is her eyes... she looks sarcastic all the time even when she is being serious

i picked Jack, i just can't stand him. He never listen to anyone, he just does what he likes to do!

Jack & Jin also annoy me.

No, really, I know she is a nice and kind person... But I just can not stand her.

who picked vincent?

Kate definitely has annoying moments... But I would have picked Sawyer if he was an option. He gets better throughout the seasons but at first, his selfishness was so frustrating!! I honestly wanted to punch him a few times.
People think Jack is annoying because he is always trying to fix things, and yes he is stubborn obviously he has flaws. but at least he tries to do stuff. The first season all Sawyer did was steal things, bitch about stuff, and have an inability to share.
