I've never played the game so didn't know the story but knew what to expect:
Plot:A secret experiment. A deadly virus. And some good guys...
Okay, its formulatic and okay if you've played the games you'll know exactly what to expect - BUT it is a great film and combines nicely action and thriller with Horror Sci-Fi. Starring Milla Jovovich (starred in Fifth Element and Zoolander) the film aint to hard on the eye either .
Although its one of those films that's ending is obviously just setting up for the next one (Resident Evil 2: Nemesis apparently is scheduled to start film later this year). The special effects are great and there aren't too many other action films at the moment either.
