Does anybody else think that scarecrow and other characters should have been casted differently?

I don't think that those actor would work.
For example: 10. Talia Head-Jennifer Lopez

Not in a million years would Jennife Lopez be Talia. She is to mainstream.
So here is my opinion:

1. Scarecrow-Robert Joy NO
2. Mad Hatter-Timothy Spall MAYBE
3. Poison Ivy-Mary Louise Parker NO
4. Catwoman-Angelina Jolie NOOOO
5. Two Face-possilby Brad Pitt NOOO
6. Ras al Ghul-Hugh Jackman NO
7. Black Mask-John Turturro MAYBE
8. Ventriloquist-Jim leikur YES
9. comissioner Gordon-Gary Oldman IS PERFECT
10. Talia Head-Jennifer Lopez NO
11. Harley Quinn-Heather Graham NO
12. سیکنڈ Ventriloquist-Heidi Klum NO
13.Bane-Booeyman (the wrestler) YES
15. Penguin-Danny Davido do آپ mean Danny DeVito?
16.Harvey Bullock-John Goodman YES
17.Renee Montoya- Judy Reyes NO
18. Slade Wilson-Robert Englund YES
19.Oracle-Julianne Moore NO (too old)
29. Carmine Falcone-George Clooney NO
21. Ratcatcher-Tim Blake Nelson YES (but do we really want a Batman movie with the ratcatcher as the villian?)
22.Warren White-Bruce Willis MAYBE
23. The huntress-Monica Bellucci YES
24.Mr. Freeze-Patrick Swayze NO
25. Lady Shiva-Lucy Liu YES
26. Batgirl-Daniele Suzuki YES (As Cassandra Cain right?)
27. Azrel-Steve Byers NO
28. Mr. Zsasz-Jude Law MAYBE
29. Joker-Conrad Veidt (If he wasn't dead) YES
30. Killer Croc-Derek Mears YES

yes they need too.

Just to tell you, Batgirl is Oracle. There is no مزید batgirl because she got shot in the spine سے طرف کی yours truly, The Clown Prince of Crime

Ha! Robert Joy and Lopez, you've got to be kidding me! Worst فہرست ever.

every has their own opinions so if that's who she thinks should play who that's her thoughts. don't judge other people on their beliefs.
