Pirates of the Caribbean 3: skip it. Seriously. Its about 3 hours with maybe 12 minutes - maybe 8 - of slight fun. Horrible script on a truly unfollowable and dumb plot. Just awful.
One question: the second movie was much worse than the first, though much better than this one. Its strongest sequences, by far, where the daffy feats of kinetic gymnastics that the characters performed in a series of chase scenes and sword fights. And what really set them apart was that except for single set shots, they weren't computer generated. They were real stunts.
The sword fight inside a runaway, rolling waterwheel - the combantants dueling as they run like hampsters inside the wheel - was the best live stunt I've seen this decade. It felt like an 80s action movie. Brilliant!
This movie has so little real stunts/action versus absurd - truly awful - CGI, you might as well just turn you iTunes onto tht funky visualizer that makes your computer a kalediscope. Its just as real as any of the 'action' in the dreary Pirates3, with better music.
