I am guessing though, that despite director Bryan Singer's claims to the contrary, he was merely settling in to do the sequel. Kind of like X-Men was little more than a long set-up for X-Men 2 - one of the better action movies of the last two decades.
And maybe like how Pirates of the Caribbean: Curse of the Black Pearl was a set-up for Pirates of the Caribbean: Dead Man's Chest. I'm with Jeffrey Overstreet on this one, DMC was a dark but thrilling second act. Although my butt didn't too much care for this other 2 1/2 hour slug-fest, it was an action piece that's got me wanting more moody, Empire Strikes Back-esque/carnival ride movies for the new millennium.
I'm a pirate, that I be.
Here's to hoping the next Superman is sublime and the third Pirates actually fulfills the ideal of the trilogy, unlike say X-Men III, The Godfather III or Return of the Jedi. (Damn you, Ewoks!)
