Adam Sandler's new comedy may be intensely mediocre, but that's still a big step up from the intensely unwatchable comedies he's produced this year. (See---or rather, don't---Just Go with It, Zookeeper and Bucky Larson: Born to Be a Star.) Sandler plays both title characters: a struggling adman and the vulgar, oafish twin sister who becomes his unwanted houseguest. Admittedly, the film is merely a series of random celebrity cameos and shameless product placements. (In one case, both---thank you, Jared from Subway!) But there are a few moments of inspired absurdity, mostly provided by a surprisingly energetic Al Pacino, playing himself and channeling Some Like It Hot's smitten millionaire Joe E. Brown, as he falls head over heels for Jill.
