Just a few points to add before I sign off.
1.If you think you won't like the movie, stfu and don't watch it.
2. M.J. White would make an excellent green lantern, but this isn't about the new one, it's about the old one. Its not about racism, get over it.
3. Ryan probably would make a better flash, due to his current image of having that flash type of attitude, but I'm sure he can pull off a more serious role while maintaining his quippy nature. Hell, maybe he's doing it to change that image. Jim Carrey did a great job of doing that in the Movie '23' in my opinion.
4.It's going to be a good movie for what it is, which is yet another directors conception of what green lantern should be. Face it, they'll never stick exactly to the story in comic/videogame movies (they have, but I can't name the few movies that actually did atm.) Once you get past that, you can watch the movie with the eyes of a nub that doesn't know anything about the story and enjoy it.
5.All we really can do is hope that it doesn't suck. I for one hope it doesn't, and further hope my hope isn't misplaced like when I hoped DB Evolution wouldn't suck.
6. If the trailer was that damned bad, I really hate to ask what YOUR OPINION of a good movie let alone trailer is. >.>
