I cannot wait till the movie comes out. I don't know if i will go on the opening weekend, I don't like how packed it always is on opening weekends. If you're like me and like a little bit of spoiler bits, or just some things to fill you in on what you may need to know before the movie comes out go to

There are also some comic books that came out that tell what happens between the first movie and second to fill you in. Its said that the movie jumps right into the action and if you don't check out the comics you may be left with a few questions at the beginning.
The comics are the Alliance and Defiance comics. I do believe after the last of each issue comes out there selling them as a package deal. Idk though, I will have to check back to see if the last of them are out yet.
