I love the original an awful lot lol. The second one was awful IMHO. The third one was okayish, fourth one... meh, it was terrible. It barely felt like POTC...

So yep, I can only really enjoy the original. The rest are a big meh to me. They should have stopped at the first one, it didn't need a continuation.

(Although I gotta admit, Jack Sparrow cracks me up in all 4 movies. xD)
