To be honest I went into this with low expectations and somehow it went below my already low expectations. With Jet Li being the only redeeming value, and the only reason I saw this, there isn't much this movie offers.
Cradle 2 The Grave is about a jewel thief's daughter who is kidnapped after he steals a collection of prized black diamonds, and that's the closest thing you'll get to a story from this movie. This movie was literally a boring experience for me. It had no interesting characters, no funny comic relief, no focus, and most of all no interesting ideas. This is literally one of the dullest action movies I've seen and lacks excitement in every way possible because the heroes come out invincible. I also didn't care for the characters either, heck I didn't even care about the little girl who got kidnapped as these characters are so thin and poorly written. It's story lacks everything you expect from a enjoyable action movie, even with low expectations it still failed to be engaging.
Now the only person that prevented this movie from being abysmal is Jet Li. Unfortunately he doesn't get many lines, he doesn't get to act, and is only there to fight. Which is another downside as Jet Li Martial Art skills aren't use properly and his fight scenes come out poorly done. I'm serious, not even when Jet Li was using a midget as a weapon gave me any kind enjoyment. Well to be fair to Jet Li he's the only actor in this movie who came out enjoyable and it's a shame that he had to share screen time with these other actors who put no effort in there parts.
Cradle 2 The Grave is a dull action that has nothing interesting to offer, with Jet Li unfortunately being limited in his appeal. It's a boring action movie absolutely not worth your time.
