Daniel Radcliffe fans, at least the ones who care about him as an actor and not as Harry Potter, will be gratified to learn that he gives a performance in “What If” that will in no way remind anyone of the boy wizard. He plays Wallace, a med school dropout in Toronto who, still reeling from a breakup with his girlfriend, falls for Chantry (Zoe Kazan), a gamine animator who inconveniently has a boyfriend (Rafe Spall) but wants Wallace to be a "boy friend."
This is standard rom-com terrain, and, as directed by Michael Dowse and written by Elan Mastai, it doesn’t fly high. At times it’s rather sweet, though, and Radcliffe and Kazan have a nice nerds-in-clover rapport. If only the movie wasn’t so satisfied with how cute it is. Grade: B- (Rated PG-13 for sexual content, including references throughout, partial nudity and language.)
