I saw the movie last night but was a little disappointed.
The movie was unnecessarily long and overall I didn't think it had the magic of the original. Most of the verbal jokes were just takes on the jokes from the first movie, and in particular, the rum joke was overdone. Some new additions to the soundtrack would have been nice, as the only one of note was the organ track for Davy Jones.
Most of the action scenes felt very over the top, in a way that the filmmakers were trying to top the original but ended up going too far. Leave the hamster wheel sequences to Cirque du Soleil. That, and the drama was pretty lame.
I know I've focused on the elements that I thought were weak, but I did actually manage to enjoy the film. I definitely don't regret seeing it in theaters, but it wasn't really what I was expecting. It really seemed to overcomplicate the simple and fun movie that was the original.
I'd give it a 6/10.
Jam it back in, in the dark.
