Action scenes look horrible, but I've always liked the RE series both movies and games. They do differ from each-other, and the games that are coming out now are differing from the originals in a lot of ways. The CG effects look really smooth in the trailer, dunno how the 3D will work with it, probably horrible as imaginary depth is far from 3D.
I'll probably rent it, MAYBE see it in theaters(non-3D) if any of my friends want to see it.
If they're gonna keep making movies, something has to be done to Wesker in order to build some suspense along the way. He's always just disappeared at the end of each movie/game.
