That said, it's one of the better movies I've seen in a while.
General spoilerific type comments follow:
Only two previews... I've never seen only two previews before a movie before that I can recall.
Okay, they've already established that the languages used in the Alliance were English and Chinese. The writing in the ship in the series was Chinese. The writing used everywhere else was Chinese. Why, then, was the writing in the ship Japanese in the movie? Yes, it's easy to tell the difference.
Killing off Book? I mean, come on, he was one of the most interesting characters on the show. And now we'll never know what the heck was up with him with that enigmatic history and all. Between that and Wash... Well, it was a bit shocking, which is good, but... Book?
The opening bit explaining the Alliance made a lot more sense than the series. Not scientifically, of course (it's kinda stupid, and it was definitely the weak point of the whole shebang, and probably the main source of the illusion my old housemate has that Battlestar Galactica is better :), but it was never very clear before.
And yes, this was the first time I've seen a movie in a theater solo in my entire life.
