Wasn't What It Should Have Been First off, people need to stop comparing this to Resident Evil. Resident Evil is about monsters and explosions. Silent Hill is about psychology, deep depiction of characters, the metaphysical, spirituality, and mystery.
With such drastic differences, Silent Hill had massive to potential exceed any or all video game crossover films. This formula of conceptual delivery is mixed in with ambiance, surrealism, and monsters that derive from the characters own minds. It's not just random happenings of gore, at least in the game(s).
This film fails because of its overblown plot, inherently poor melodramatic acting, and dialog that seemed unintentionally comical. Some of the people sitting next to me in the theater giggled at a few of the lines. And those who seem to be bored with everything, were either confused or not interested in thinking at all.
Most people just want mindless action derived from nothing, while they choke on popcorn and suck down sugar water. I am quite disappointed for the SH franchise.
If there will be a sequel, I would hope the filmmaker chooses a wiser approach:
SIMPLIFICATION. PLOT ACCESSIBILTY.
