Unpredictability is a key element of humor. Part of the problem with comedy sequels is that you know most of the jokes already. “Austin Powers: The Spy Who Shagged Me” (1999) is like listening to a greatest hits album. It’s well crafted and true to the first installment of the spy-sendup franchise, but that’s also the problem. You want some new stuff, too. And that’s another problem. Heather Graham is great as Austin’s American counterpart but the Fat Bastard and Mini Me characters are so creepy and get so many scenes, it makes the whole thing predictable AND kinda gross.
