I'm really bad at critiquing movies, but.. I think it was okay. Not as good as the others, though. I've talked to people who also saw it and most of them were disappointed and say it wasn't as good as the previous movies. Some parts were funny, but most of it seemed like it was just a lot of sword fight scenes and/or Jack getting chased by people. Then again, weren't the previous movies like that too? lol. Honestly I hardly remember details from the movie, and I just saw it on Sunday.. This is probably due to the fact that I hardly slept that night so I was dozing off during the movie (when the mermaids weren't screaming their heads off). From what I remember about it, I'd probably give it... 7/10.
