This is going to be quick, since i am actually at work today:

Pirates of the Caribbean: At World's End
Very good movie. Not great, but worth seeing in the theater (even a non-digital one).
However, it was much like Spiderman 3, it took a jump to the goofy side several times that is going to make it hard to re-watch.
Overall, i was gratified to find that it lived up to my expectation as a very similar trilogy to the original Star Wars trilogy. First movie is fun, beat the bad guys, could stand alone. Second movie is much much darker, and our scoundrel hero dies/disappears in the end and the rest of the team (young and fragile) is left all alone in the world. Third movie they first have to come of age on their own, go rescue the scoundrel, and the audience has to deal with silliness (Ewoks and split personalities) and there is a major battle at the end.
Of course with Pirates, the ending was a little more complicated and slightly less obvious than Star Wars - and not quite as completely happy, but solid overall.
Last statement is that the writing stayed fantastic. The pace was good, the plot twists did not disappoint, but were not impossible to follow, and the dialog was appropriately simple/complex for each character. Lots of good quotable quotes from Captain Jack and other characters without being too silly (most of the time).
I will also say that i went back on my promise and watched this movie on film (at Opry Mills) but the experience was tolerable. Much better than my previous film experiences. However, my friend (one that i drug with me to see Spiderman 3 in digital) leaned over to me after the movie and cursed me for spoiling him. He had never thought film was bad until he saw a movie in digital. This was a great film showing, the sound was good, but there were still flecks, the light still flickered, and the picture still shifted laterally and in and out of focus. We'll see where we end up going to see our next movie on the list (Ocean's 13 is probably next), but i have a feeling it will be digital. No question we'll see Ratatouille in digital, but my hope is that we wont have to goto the ghetto to see it - Opry Mills was showing Shrek 3 in digital last night (but everything else on film).
