Matt Singer’s review published on Letterboxd:
An inauspicious early work by Mick Garris, who is known for horror and probably would have made something more interesting had he gone that route with this story of a misunderstood kid and his invisible friend. Fuzzbucket himself is certainly scary enough for a horror movie; his design is pure nightmare fuel, even if the movie treats him like an adorable imp. (He looks like the love child of ALF and a really gnarly sewer rat.) If the invisible friend turned out be a murderer or a figment of a violent kid’s imagination, that could have been something.
