After We Collided borrows lines from Wuthering Heights, but its resemblance to Twilight and 50 Shades of Grey is more accurate (the initial novel, After, which this film continues, began on Wattpad, a platform where anyone can publish, regardless of their suitability). Unlike Heathcliff and Catherine—and by extension Romeo and Juliet, the originators of all star-crossed romances—Tessa (Josephine Langford) and Hardin (Hero Fiennes Tiffin) face no real obstacles to being together beyond the fact that they are fundamentally incompatible. The only spark between them is physical; After We Collided has more overt sexuality than Twilight but isn't as daring as 50 Shades—there’s a lot of suggested intimacy, though very little nudity. Because there's no logical reason for these two to be paired, it doesn’t really matter if they don’t work. The movie does attempt to create a justification, however; Emotionally Scarred Bad Boy Hardin (Tiffin is Ralph Fiennes’s nephew, but looks more like a younger Joshua Jackson with a British accent) experiences nightmares that disappear when he's dating Tessa. This explanation feels completely fabricated—intimacy doesn’t guarantee better sleep. This reflects the film’s simplistic belief that love can overcome anything. While love may resolve many issues, it cannot resuscitate a plot that is dull and lifeless. The only aspect of the screenplay that makes sense is the title itself, as the events unfold without any real feeling of importance. Nothing gets settled in this movie; everything is postponed—to the point where two more installments were planned when this one came out.
