I really hope it does well (cause I love Hal and the rest of the Gls and there's such great potential for sequels since the Corps is so huge and gah getting to see Sinestro really shine as a villain would knock my socks off) but also because I think it would help pave the way for more DC movies about people other than Superman/Batman.
Ugh Jonah Hex, why were you so bad.
I really want a Flash movie, because he's one of my faves. And yeah Sinestro is totally awesome when Geoff Johns writes him, as is Captain Cold. Say what you will about Johns he does a great job with DC villains.
