Even though this forum about bad taste has turned into a will-they/won't-they relationship about the Pirates trilogy, I'll continue on the tangent.
COTBP is one of my favorite fantasy films because Jack Sparrow is only crazy in small bursts. They even hang a lantern on it with the stories of how he gets off the island that Barbossa left him on. Love, love, love that movie.
DMC, however, fell short (or considering the runtime LONG) on my expectations.
Something was brought up to me not too long ago and I think it rings pretty true: Will and Elizabeth's story could/should have ended in the first film and the sequels could/should have been about how Jack Sparrow effects people's lives while learning about his past.
Be that as it may, I hated the love triangle aspect (or pyramid when you add Norrington) and I hated the fact that by the time they reach the chest I think the movie should be almost over.
The only redeeming qualities to the movie are the inventive set pieces, the aforementioned "jar of dirt" dance, and the big reveal in the last 2 minutes of the film. Other than that, I found it pretty "meh".
AWE is dead to me. Just recently watched all three of these (USA network had them playing back-to-back) and I honestly did not remember a single thing from the movie except the whirlpool fight (and even that is just fleeting memories of swinging from ship to ship).
