+1
To be honest I thought Pirates 4 was a big improvement over the last 2 sequels, though still no where in the same league as Pirates 1.
Even though the original cast was charming, Pirates 2 and 3 had just convoluted the original plot and characters so much that it was better to just scrap everything and start over from scratch at that point (not to mention 2 and 3 pretty much undid everything established.the 1st film - turning Barbossa into a 'good guy', portraying Jack as more cowardly, screwing over Will Turner with the ending, etc).
Pirates 4 was forgettable but it wasn't awash with mind-numbing CGI and unnecessary plot twists that were impossible to follow. So yeah, #4 is a step back in the right direction, though I'm not holding my hopes up for the 5th one.
