I just finished watching this, and I was pleasantly surprised. It's about 5 people who get trapped in some sort of ancient-like dungeon. There are a couple different rooms they have to get into in order to escape the gauntlet - which was the original title of the movie - and each room has a puzzle they have to solve before they can advance. Generally, a blood sacrifice of sorts has to be made.
Bai Ling (Red Corner, The Crow) and Warren Kole (24, The Following) lead the cast. This is probably the first movie since Red Corner that Bai Ling has been in in which she did not play some tramp, slut, or bimbo. She was actually allowed to act, and she did a good job. Plus she looks really good. She's close to 50, but looks half that age. I always thought she'd be a Chinese superstar like Li Bingbing and Xiang Ziyi, but for some unfortunate reason that didn't happen.
There are deaths in this movie, which I knew there would be, but I was still surprised at some of those who were killed. I can't say this was all that original, but it was pretty well done for what it was. The poster for this film doesn't make much sense when compared to the actual movie.
I recommend this movie. I gave it a 6-star rating. I might revisit that later, but I tend to rate a movie based on how I feel right after viewing it. Perhaps this deserves more like a 5-star rating, but even though the material has been done before, as I said earlier, they did a good job on it.
