Tom Cruise's better half is certainly beautiful enough to make it believable that Ted (Josh Radnor) would track her down a decade after meeting her at a rooftop costume party. But her blandly polite line readings — Holmes' "acting" seems more like personal appearances these days — undermined the story line's single joke: that she and Ted had no chemistry.

Holmes' next big-screen role (which the HIMYM gig was clearly meant to promote), as Adam Sandler's wife in the godawful-looking Jack & Jill, likely won't prove any more enjoyable.
