Hank (Fredric Forrest) and his girlfriend Frannie (Terri Garr) have a relationship that’s constantly fluctuating – together, then apart, then back together again. After five years of this pattern, there's affection present, but also considerable unease, and it's that restlessness which eventually leads to their separation. She begins a connection with Ray (Raul Julia), while Hank finds himself drawn to Leila (Nastassia Kinski). This latter pairing turns out to be the slightly more diverting aspect of this otherwise forgettable drama. Leila works at a circus, performing dangerous stunts in a large tent that’s obviously just a massive sound stage. That's where this film distinguishes itself somewhat – it was entirely filmed on a set. The presentation is akin to watching a play, complete with lighting transitions and music used to bridge the scenes. While the production design and special effects are effective in establishing that atmosphere, they can’t overcome a fundamentally weak narrative that neither Garr nor Forrest manage to elevate significantly. It's a five-year itch romance that seldom elicits humor and feels entirely artificial throughout. I don't question Francis Ford Coppola’s intention, but it seems more like an exercise intended to demonstrate his ability to create something deliberately contrived and impersonal, rather than a sincere attempt to connect with the audience in any substantial way. The characters lack depth and development, and despite my best efforts, I simply didn't find myself invested in their stories – either positively or negatively.
