I really donít have anything specific to complain about other than I feel like Iíve seen it before. The acting lived up to the (very low) expectations. The creatures were scary looking and there was a fair amount of suspense and drama. However, I feel like there could have been a lot more depth to the story. They had a decent idea going on, but they sacrificed an eerie idea and back-story for cheap thrills and over-used scares. The opening touched on a crusades-era story that was never really mentioned again.
The movie also feels very rushed. Itís like they had more to throw in, but they were trying to keep it around the 90-minute mark. I donít think they couldíve done too much better, but it could have been a little more tolerable.
Commentary with Michael Steinbrg and Tegan West: These guys wrote the flick and theyíre pretty proud of it. They talk about interesting stuff and Iím left wondering why they didnít include more of it into their script.
