mini-review: "Night at the Museum: Battle of the Smithsonian" [B-]

I liked this movie. It was an enjoyable way to spend an evening, the sequences were fun to watch, but it had too many plot holes. It started with the obviously preposterous setup used to send the characters from New York to D.C. The rest are all too numerous to enumerate in a mini-review, but basically boil down to my befuddlement over how Washington D.C. could seem so utterly devoid of security. What? There's nobody around to notice that a 50 foot tall Abe Lincoln is wandering the streets? Fun is fun, but... huh?
