Well, it appears my subconscious wants to guarantee that I enjoy it, because there is no way that the real thing can fail to improve upon the version that I just dreamed about walking out of halfway through. It featured:
* Sarah Palin playing a "heroic" character that was, basically, herself;
* While wearing a long blue dress showing lots of leg and cleavage;
* Lots of corny self-aware jokes about it being a movie;
* and a bunch of characters breaking the 4th wall to argue with the audience that it's a better movie than they think.
So... thanks, brain, I guess?
