Rampage and the Man with the Iron Fists

Action movies that are unbelievable? :P

Rampage

When cutting edge, experimental genetic alteration experiments end up in the wild it turns a number of creatures into gigantic, angry mutants. Luckily the protagonist primatologist (played by Dwayne Johnson) is on the case, complete with cheesy lines and death defying feats of "no one should have survived that".

In all fairness I'm surprised they managed to get an OK script for something that's based on an old cooperative arcade game which soley focused on destroying cities. With decent CGI it's certainly entertaining as long as you turn your brain off.

The Man with the Iron Fists

Jungle Village becomes the cauldron of wire fu martial arts and ridiculous weaponry when various clans vie for control of a caravan full of gold that comes through. Embroiled in the middle of it all is a master weapons blacksmith (RZA) who happens to be supplying all sides.

"Spectacle" is probably the best word to describe this, and while the plot is so / so it features many good action sequences (even if some are hilarious)  and a good amount of gore which always gets points from me. I'd say Rampage is better than this movie, but if you like martial arts and wire fu you should definitely check this out afterwards.
