The only game I know by Double Helix was Silent Hill Homecoming. I liked the game, but it didn't exactly make me a fan of Double Helix. I guess we'll have to wait and see.
Regarding the GL movie ...
Me excited. I love the DCU animated movies coming out. So far they've all been great. Final Frontier was fabulous. Even the Wonder Woman movie that came out a few months ago was surprisingly good. What I've read/seen of the new Green Lantern movie, I like.
