UltimateMovieRankings’s review published on Letterboxd:
Another visual stunning movie from the late and great Satoshi Kon. Story is more than confusing but the movie never slows down enough to let that be a problem. Movie takes place in the future and dream therapy is a new technique. Dreams on top dreams on top dreams....hey that sounds like Inception.....but this one is 4 years before Inception. Makes you wonder if this helped spark Chris Nolan to the Inception world. If you like animation then this is the perfect movie for you.
