There are some movies that did a pretty good job in small details, but failed in the big picture. The long-waited sequel of the big hit in box office, Night In the Museum 2, unfortunately joined the club here.
Ben Stiller's influance in Hollywood is obvious -- just look at the whole group of ppl he summoned for this carnival-like movie! It seems that he wants to make it another Ocean's series. But my suggestion is, next time, write the scripts yourself, Ben.
Similar to the original one, this sequel movie tells the "battle" in the biggest museum of the world -- National Archives of USA, located right in the heart of Washington D.C. We know that the story is predictable, but the effort of trying to improve that by adding a whole bucket of patriosim, a classic Hollywood version of "the man saved the day and got the girl", several pieces of funny talkshows (OK, they are NOT that funny, actually) and the most IN items such like the Jonas Brothers (but they really look cute... pardon me...), is not effective here at all. 99% of the audience are here for Ben Stiller, not a freak lady pilot crazy for whatever man she saw. I'd rather to see some more scenes about the little boy playing Ben's son.
Some jokes are too abstract for foreigners and even some Americans. The last scene about Motorola mobile phones is so ironic -- I'm pretty much sure that we will see this end of this once-holy brand quite soon.
