A group of scientist/explorers are brought in to explore a cave in Romania. Legend claims a church was built to seal the cave as a display of God's protective power, and Templar Knights fought winged demons.
The acting is pretty good with some solid actors. The most recognizable actors are Lena Headey, Morris Chestnut, Daniel Dae Kim, Cole Hauser, Piper Perabo, and Eddie Cibrian. They're able to give serious performances without being campy.
It's not scary as a horror, but it works more as an action adventure. They could have laid out the cave system better as the movie goes along. A few seconds of screen time could save a whole lot of headaches. Seeing Piper Perabo swinging on the cliff is a lot of fun. However some of the other action scenes are too confused and chaotic.
The creatures are a bit of a disappointment. It's just yet another CG creature creation. Half lizard half dragon, it could have been so much better considering what the creatures are derived from. They could have made it much more original and unique.
