Megan Fox and Shia LaBeouf in Transformers: Revenge of the FallenWithin the first minute of Transformers: Revenge of the Fallen, it'll be pretty apparent that the movie wasn't exactly designed for (or by) Mensa members, as a title card shows the military time in China to be 22:14 hours, and the sun is still up. It'll quickly be even more apparent, when the prelude's autobot narrator mispronounces "refuge." But heaven knows we're not expecting braininess from a Michael Bay-directed action sequel based on a line of Hasbro action figures; if the effects are sufficiently awesome and there's a good joke now and again -- which pretty much sums up Bay's original, 2007 Transformers -- nearly any other irritant could be easily forgiven.

Ben Stiller in Night at the Museum: Battle of the SmithsonianNIGHT AT THE MUSEUM: BATTLE OF THE SMITHSONIAN

Night at the Museum: Battle of the Smithsonian is to its precursor what Ghostbusters II is to Ghostbusters: the less-novel offering, sure, but a follow-up of surprising wit and great throwaway touches, and one that, in many ways, improves on source material that was pretty terrific to begin with. Despite its titular locale, no one is going to mistake director Shawn Levy's adventure comedy for a work of art, yet when this follow-up is really working - which is surprisingly often - it provides a giddy, giggly rush, and it's filled with comic bits that you could probably watch three or four times in succession and laugh at every single time. The movie is scrappy, silly, and a load of fun.
