Animation is not bad but not like the original characters. The characters that represent the originals don't even acknowledge what the virus is in the beginning of the movie and the DVD case calls it the G-virus. For a video game, where you focus on the action and not the characters details it's OK, but for a movie, they should have done it with people. The CGI quality is not that good to say the least. The lip sync is very bad. I'm glad I got this as a freebie with my monthly subscription at the video store and didn't have to pay to see this. If they do a remake with the original cast (the survivors anyway) this movie might kick butt like the other ones did.
