The tagline for this tolerable comedy, directed by Ivan Reitman (Ghostbusters) from a script by Don Payne (The Simpsons), could be Hell hath no fury like a superwoman scorned. Uma Thurman plays a neurotic female version of Clark Kent who has trouble holding her superhero powers in check. A lot of superwimp gags executed by Luke Wilson grow out of this premise, as do some tacky 50s-style special effects. The movie’s too slapdash to keep its characters consistent, but this has its moments. With Anna Faris, Rainn Wilson, Eddie Izzard, and Wanda Sykes. PG-13, 95 min. (JR)
