One was alright. Two and three were a waste of time. Davey Jones was a wasted villain. The series is a great example of an over-ambitious writer and director. They tried to do way too much plot-wise, and ended up with half-assed drama and way too many attempts at witty one liners. Even the first one suffered from this a bit, albeit it was structurally sound in the end. Just because something is popular does not mean people hate it to seem cool. Many people just have higher standards of entertainment. I could make the same claim at you both for not liking Twilight, which is definitely more popular.
I for one, do not enjoy Harry Potter in book or movie form. Both I find to be incredibly boring as it is not of my proffered genre. I find Johnny Depp's acting to be average. The only performance of his I can honestly say I have enjoyed was Willy Wanka in the Chocolate Factory, and I disliked that movie. Even then, he just rehashed a performance of a character he has done before. Again, different people, different standards. It is an opinion.
