Losing streak: The Wedding Planner (2001), A Walk to Remember (2002), Bringing Down the House (2003), The Pacifier (2005), Cheaper by the Dozen 2 (2005), Hairspray (2007), Bedtime Stories (2008), Rock of Ages (2012)

Yes, Adam Shankman’s 2007 box office hit Hairspray did receive mostly positive, glowing reviews, making it a possible reason as to why he shouldn’t be included here. But, come on—Hairspray? Really? Sure, it’s well-meaning and energetic, but for a story about sexual awakenings, there’s a serious lack of provocation. It’s a Sex Ed class held on the High School Musical campus, taught by neutered professors.

Yet, it’s also infinitely better than Shankman’s latest song-and-dance grater, this summer’s two-hour-long, plot-less Rock of Ages. Little more than a karaoke exhibition acted out by Tom Cruise and other big-name stars, Rock of Ages skews much closer to Shankman’s pre-Hairspray films, unendurable “comedies” like The Pacifier, Bringing Down the House, and The Wedding Planner.
