Saw it last night. I must say that although it was fairly well done, there was definitely something missing.
Everything was so unbelievably impossible that after a while you think "yeah, he's going to die unless he can kill those 30 people, jump off the 50 foot cliff into the boat, strangle those two guys and then punch out some sharks" -- no problem.
There was certainly some good camera work, but there was a whole element of "fun" that just didn't exist. Good stunts, but poor atmosphere.
