I saw it a few months ago. It was pretty so-so. Basically the second half of the film was pretty boring. Like RE5 said, talking and talking. Also, only the first half of the film featured zombies and the second half focused only on Curtis Miller. But it's Resident Evil, I didn't actually expect anything over the top on the story aspect. But again I'd have to agree with RE5: Make sure you're alive and wake when you watch this film. That's the mistake I made. I watched it at about 3 a.m when I was dead-sleepy and I had like 40 minutes to go. I didn't want to stop watching because I had hoped something cool will eventually happen but all that happened, was just predictable... Ok so a little plot-twist at the end, still not worth forcing your eyes to be open for.
But overall it's worth watching if you're a Resident Evil fan, because it further tells the story of Leon and Claire.
Also, Leon seemed to be aiming his interest towards a new woman as opposed to Ada from the games.
