The One I Love is billed as a ‘comedy’. But I think the real problem this directorial debut of Charlie McDowell (son of) has is that it isn’t quite sure what it is trying to be.
This is a movie definitely best watched with as little knowledge of the plot as possible, so I won’t explain much more than this: A couple is undergoing marriage counselling, and their counsellor sends them off to a private retreat that will work wonders.
