I felt that it was done very sloppy. Editing kinda was screwed up in places, not to mention the fact that characters were in one shot together and in the next separated across a room (or cavern in this case). Oh yeah, and theirs nothing like continuity goofs, but who here can crash a truck into a wall, bash the windows and rip the wheels off and in the next second be back to pre-wreck?
The direction was okay at best, there wasn't much "character" in the actors to make me like them or hate them. I found myself just bored.
The miniature sets (ship, dock, castle...ect) looked cheap and "B" movie finished (the boat was sailing through water that had drops the size of a scaled person (or car).
I thought the CGI was standard grade as well...
All in all, I would give is an average rating. 5/10.
NOW THE SILENT HILL TRAILER WAS AWESOME (though it had CGI problems--- but it has months to go so I can see improvement).
