This second POTC adventure is, like its predecessor, full of action, humour and brilliant sets/locations and special effects. However, DMC has more concurrent individual character arcs/subplots, deception, backstabbing and allegiance-switching than you'd see in an entire season of "24", which can make things a little confusing at times. The result is an epic maelstrom of excellent CGI, beautiful locations, MacGuffins, Easter eggs, a possible homage to Return of the Jedi, and plenty of over-the-top antics (even by the standard he set in CoTBP) from Jack Sparrow - all culminating in an unsatisfying ending which was clearly just paving the way for the sequel. The saving graces that makes this film high quality and well worth watching are the excellent acting, the non-stop action and the light-hearted humour.

I kept thinking all throughout this film (more than any other POTC film) that Disney may have been raising a jug of rum (or maybe a mug of grog) to the 1990's graphic adventure games "The Secret of Monkey Island" and "LeChuck's Revenge: Monkey Island 2" from LucasArts (a franchise which Disney subsequently purchased) as there are many similarities:
1) A charming-but-foolish protagonist (Will Turner in DMC / Guybrush Threepwood in SoMI) who has recently become a pirate is chasing after the love of his life (Elizabeth Swan / Elaine Marley) who is herself a sassy, witty, piratey, stunner.
2) Turner-wood is trying to rescue Swan-Marley from the evil clutches of a mangy, dead pirate captain (Davy Jones / LeChuck).
3) Jones even looks a bit like the zombie pirate LeChuck - other than by being a mangy, dead pirate captain - in that his beard is tentacular and wriggly.
4) Jo-Chuck's ship is a spooky, fearsome vessel crewed by undead pirates.
5) There is a black voodoo lady with a strong Jamaican accent who gives cryptic advice on what to do.
6) Artefacts have to be collected to control/bring down the undead evil pirate Jo-Chuck.
7) Jack Sparrow's antics would easily be within the realm of those performed by Guybrush Threepwood, but GT has been divided into two characters in POTC - Will and Jack.
No doubt there are other such similarities between these two franchises which I have forgotten about/haven't discovered yet, as I have only completed the first two MI games, and half the third. I would heartily recommend playing them (remastered versions are available on Steam and GOG), if you haven't done so already.
