Went to see Resident Evil: Retribution yesterday. Overall, it's pretty terrible, about what I'd expect from a Paul W.S. Anderson film (about the only thing I can say about him as a director is at least he's better than Uwe Boll). There's enough in it, I think, to be enjoyable for fans of the series (of which I only liked the third film).
What I did enjoy about the film: the sound design; the photography; the opening sequence; a couple of the fight scenes; Milla Jovovich; hearing the names of RE game characters.
The overall concept of the film, I thought, was decent. The problem, however, lies in the moment-to-moment. As clever and inventive as some of the action can be at times, there is twenty times that much of clichés, poor dialogue, disjointed storytelling, orphaned incidents and just plain stupidity. Bottom line: one Milla Jovovich, a couple of great action scenes, and hundreds of poor decisions.
