There’s maybe a single scene in World’s End that I thought worked, that was genuinely enjoyable, clever, and well staged. Unfortunatley, that scene comes more than two hours into the movie, and then there’s another forty minutes to go after that. I think Scott Tobias of the AV Club sums it up nicely:

The Pirates Of The Caribbean trilogy — and At World’s End especially — stands as a lesson in the perils in blockbuster filmmaking: What started out as a fleet one-off swashbuckler with novel supernatural elements has become loaded and graceless, with each new entry barreling across the goal line like William “The Refrigerator” Perry. The franchise’s two chief assets — the surprise of Depp’s swishy pirate and Gore Verbinski’s dexterity at directing slapstick action sequences — have been eclipsed by expository scenes that confuse even more deeply in their attempt to clear things up. Should the franchise warrant still another sequel, the dialogue might as well be in Esperanto.

And not to give too much away, but the movie definitely does set itself up for a sequel.
