The movie is a prequel to the game and actually animates some of the events you see through the video journals in the game, albeit not accurately. There is a TON of swearing, it seems to eat up half the dialogue of the movie haha. It's not bad.
The game itself was fine, I enjoyed it but became way too bored with it in the long run; I beat it and the storyline had a great twist, as any good horror game does, but I sold it to somebody else so I could buy Left 4 Dead instead.
Prefer Resident Evil series.
