Rarely has the euphoric delirium of new love been rendered as believably as it is in the opening act of Drake Doremus’ Like Crazy, as college-age cuties Anton Yelchin and Felicity Jones tumble hard for each other. This giddy first burst, and the chemistry between the actors, sustains a movie that runs into trouble at about the same time as its protagonists. Jones’ character is a student who overstays her visa and gets booted back to England, condemning the couple to a long-distance relationship interrupted periodically by hookups with more geographically convenient partners (Jennifer Lawrence and Charlie Bewley). Doremus treats these secondary characters like wallpaper, wasting Lawrence in particular. Still, thanks to Yelchin, Jones and a verite style, he fashions a heartbreaking romance that’s built on naturalism but feels like fantasy.
