I watched it last night. My impressions:
Not far into the movie I looked at M and said, "I know Emma's loves pirates, but she's not seeing this movie till she's thirteen!" The grossness and scariness factor is just too much. Lots of violence too.
I would say the third movie
had the same swashbuckling and plots twists of the other two, without any of the fun. Even the appearance of Keith Richards as Captain Jack Sparrow's father was anti-climactic. The ending was a downer. It isn't required to be happy/shiny, but sheesh. I don't know, I felt let down. Oh, and the color cast of the whole film was distracting. Everyone's face was yellow in the nighttime scenes.
