Home video review: Daniel Radcliffe and Zoe Kazan in 'What If'

Daniel Radcliffe, still boyish at 25, conjures a bit of magic in the romantic comedy "What If" co-starring Zoe Kazan, who's 30 but looks a little like a girl playing dress-up with her big, bright eyes and irrepressible sense of wonder. They generate nice chemistry as two slightly awkward introverts, Wallace and Chantry, who bond over Magnetic Poetry while trying to avoid small talk with strangers at a party. To its credit, "What If" isn't entirely formulaic. For one thing, the requisite obstacle between Wallace and Chantry's happily-ever-after is her perfectly pleasant (if protective) live-in boyfriend, Ben (Rafe Spall). PG-13 for sexual content, language, partial nudity
