I saw Pirates recently too, and I have the exact same sentiments (except I didn't think the parts on the island were that funny). The movie was very confusing, and was almost an exact copy of the first one (which is much better). We'll have to wait for Pirates 3 to tie up all the loose ends the second one left.
I also saw Happy Feet in theatres yesterday. Everything looks amazing (especially the penguins). The story might be a little hard to follow for little kids, but is enjoyable enough that the whole family can stand to watch it. The ending was kind of wierd though.
