It's based of course on the Pirates of the Caribbean ride at Disneyland, which I have never been to. But! I have played two and a half of the LucasArts
Monkey Islandgames, so that is more or less what I went into the movie looking for. And I was not disappointed in this regard; pretty much all the major and minor characters except maybe the two romantic interest characters and the head of the army guy would have fit right into a Monkey Island game.
So I was pretty satisfied, although, really, the ending didn't really make sense. I mean, at the end of the movie surely everyone in the colony has even more of a reason to hate pirates than they did at the beginning, didn't they? Why does suddenly everyone LOVE PIRATES? Although, thinking about it, if my basis of comparison is the Monkey Island games then the story either shouldn't have had a real ending at all or the ending should have been totally bizarre and nonsensical. So perhaps it does not do to complain.
I drove home happy and humming piratey songs from Gilbert & Sullivan's Pirates of Penzance. It was all very cheering.
Perhaps I'll take another stab at finishing
Escape from Monkey Islandtonight.
