‘The Ex’: Different time, different name, same dreck

It has changed titles at least once and opening dates a lot more than that. But no agile marketing campaign could save today’s audacious but futile attempt at politically incorrect humor, “The Ex,” formally known as “Fast Track.”

The name was probably changed because the performance of the supporting male nemesis character — who is the ex-boyfriend referred to in the new title — outshines that of the male lead here. In this case, that’s an undaunted Jason Bateman (“Arrested Development”) as a wheelchair-bound mega-jerk stealing the movie from the hapless boob played weakly by “Scrubs” star Zach Braff.
