Fact: franchises eventually run out of steam after the first couple of movies. Proof: Night at the Museum: Secret of the Tomb.
This is the third instalment in a brand that is already quite tiresome, but it does have a few positives going for it. It is the swansong of actors Robin Williams and Mickey Rooney, for one. And that should be enough for you to want to catch a glimpse. Also, Ben Stiller has declared that this is his final Museum movie, and while that is a relief, it is still somewhat sad – one can get used to him as the obnoxious security guard at a museum.
