This image is staff-painted tempera on a window over one of the doors at the Westgate movie theater. Its mate is a giant Superman emblem. When the weather gets hot, the hot get cool, at the movies. Today we passed over Superman and went for My [Semi-]Super Ex-Girlfriend. The entire plot’s encompassed by the title. Luke Wilson and Uma Thurman are good sports; Eddie Izzard and, to a lesser extent, Wanda Sykes do some scene-stealing. Much of this movie appears to be filmed on the streets of Manhattan and those around Prospect Park in Brooklyn. This movie’s all silly, low-key fun. The best sequence, and the one that provoked the heartiest and most extended audience laughter, employs a denizen of the deep. Stay for the clever cartoon end-credit sequence.
