Three Months proved to be an endearing and heartfelt film, though I couldn't help but feel that the script unnecessarily had Caleb riding a tandem bike by himself. While it’s true that Caleb feels connected to the bike because of his deceased father, and it occasionally serves a purpose in the story—like offering someone a ride or creating an awkward situation with too many passengers—and doesn't appear significantly more difficult to manage than a regular bicycle, the concept still felt like an attempt at attention-grabbing; a way for writer/director Jared Frieder to signal how quirky his central character is intended to be. A film can certainly feel fresh and genuine, as this one largely does, without portraying its protagonist as foolish or eccentric, which Caleb isn’t. In fact, he often comes across as quite bright—so much so that it's difficult to understand why he prefers that particular form of transportation. He makes other choices that seem odd, but these appear to arise from a thoughtful understanding of people rather than the demands of the plot. Thankfully, Three Months is more about the experience itself than reaching any specific endpoint — even though part of that experience involves riding “a gay two-man bike” (and the film has a subtle sense of humor)—which initially resembles a queer take on Clerks but ultimately sets itself apart with its ability to surprise. Romance does feature in the story—and some of the most poignant scenes involve Caleb’s hesitant, youthful affection for Estha, who enjoys popcorn—though the popcorn is also a bit of a gimmick, not nearly as much as the tandem bike. However, it isn't a romantic comedy; likewise, the narrative centers around Caleb’s anticipation of an upcoming event, but by the time the three months mentioned in the title have passed, whatever information he was expecting turns out to be irrelevant, replaced by the understanding he’s gained throughout his journey.
