How many of you guys have seen Slither? That's the only James Gunn movie I've seen so far, and I thought he did a great job of mixing the humor and horror elements in that one, and I'm pretty sure we'll be getting the same here only with sci-fi action elements.
Seen it (many times), love it, and I own the DVD. Nathan Fillion was what drew me to it, but I stayed for the great horror/comedy mix. It was a shame that it didn't perform better in theaters. It would have been right at home in the 1980's, alongside the likes of "Night of the Creeps" and "Night of the Comet."
