I saw it on saturday. It's darker in tone and the story seems a whole lot less kid friendly than the first film, but I enjoyed it as a munch popcorn and watch expensive set pieces roll around kind of film.
The darker aspects I enjoyed as I dig that kind of stuff. It's very expensive looking, I'll tell you that.
Captain Jack is less charming and funny and he doesn't always land on his feet in this one, and too much of the focus is on Davey Jones' crew for me, and I thought it was a wee bit LONG.
All in all, it was pretty fun, and had some very cool stuff in there.
But be warned if you have little kids the Davey Jones stuff might scare them, and early in the film a bird plucks an eye out of it's socket. I actually heard many of the kids laugh though, but you could feel the parental tension building up.
I wouldn't say it sucked, I thought it was pretty good.
