Ben wrote:The third film, World's End, is a big splashy mess, but it's suitably epic an does at least feel as if the original trilogy has been building to this climax - the end especially is big and bold and, even if you can't always make out what the heck is going on, you can just sit back and enjoy the scale, ideas and craftsmanship of the last third particularly.
If you remember how Bilbo Baggins sort of got swept aside by the time we got to the big splashy mess of "Hobbit: Battle of Five Armies", Jack sort of gets swept aside by the time we get to P3.
We're SO wrapped up in tying up the hundred loose plot ends in the Will, Dad and Davy Jones storyline from P2, there's not much time for anything else, and then they bring in six more
important new unexplained characters from the Pirates Council, of which Jack has a little to do with, but more that they can just bring in that tribute Keith Richards cameo. (He's Sparrow Sr., get it?)
Jack wasn't even in the original book for P4, but at least they managed to invent something
for him to do.
The problem with Jack just not doing very much in P3 is that he doesn't seem to be very useful when he's not doing anything--He may be a loser, but he's an accidental genius
loser, and when he's not given any chance to prove it, he pretty much hangs around being a woozy loser, while everyone else is worrying about Will, Elizabeth and Barbossa's big missions.
The impenetrable Rosso & Elliot mumbo-jumbo reaches a point where you know Lone Ranger is about to happen next, and even if you didn't see "A Cure For Wellness", you sort of get a hint about why Verbinski won't be asked back to do any more.
