Be on alert for spoilers. Ye shall tread no further than this point! ARrrr!
Like I said, I don't remember the first movie much at all, so the characters and continuing story were pretty much lost on me, except for a few exceptions. But the action was good, the Bootstrap Bill scenes were fun, and the swordfight on the water wheel, while a bit far-fetched, was quite entertaining. I also loved the eunich joke, because I'm just a fan of eunich jokes. But I agree that it had that Empire Strikes Back feel to it. I could see the cliffhanger ending coming. The only thing I regret not seeing in this movie is Will confronting Elizabeth about her kissing Jack. I almost wanted to see Will not agree to search for Jack at the end of the movie, just to show how pissed off he was. The CG was really quite impressive, and I didn't find myself thinking about the special effects like I would with the Star Wars prequels, even when it came to Davy Jones most of the time.
So, yeah. It was a fun movie, and I can't wait to rub my girlfriend's nose in it... if she can stop her gushing long enough to listen to me, that is. ^_~
