Fuck it, the film isn't worth a full review.
Basically; Jack is used too much, Gibbs is just tagging along, Blackbeard is weird, and a poor substitute for Davey Jones, Barbossa rather pointless, Angelica is boring and annoying.. Gah. Don't even get me started on the priest and the mermaid, which the film wanted us to care about, but failing to do so in every aspect.
In comparison to Indiana Jones, this is 'Temple of Doom'. It's one plot all the way thru, with very little switching between threads. Possibly done to try and go a different direction that AWE, but done in a way that you get tired, bored, and ultimately sleepy. I know I did.
Jack is still fun, at times, but mostly, it's just a toned down version of him. Barbossa really doesn't make any sense at all, and it seems like Rush didn't even try to portray him even close to what he's supposed to be. Blackbeard was an interesting character to begin with, but I soon realized I didn't care what happened to him either. Angelica was off to a cool start as well, but I wound up hating her fairly quickly.
The mermaid made sense in a no-sense-at-all kind of way, and the love plot between her and the priest was poorly written, poorly executed, and downright boring.
Basically, none of the characters had interesting arcs, the sets are way smaller and the plotline in general left much to be desired. If you're a fan of the first three like me, seriously don't bother watching it. At least unless you're absolutely sure you want a story that doesn't need telling, with laid-back versions of otherwise great characters.
**SEMI-SPOILERS**
Honestly, the only parts I can remember actually laughing loudly to, was Jack the monkey, and Sparrow's moment with Angelica in the end.
And why the fuck did Teague Sparrow just disappear with no reason?
