Spending his free time alone, Dave creates a cardboard maze within his home, which transforms into an increasingly large and complicated inner world filled with surprises, hazards, and a mythical beast. The initial concept—simple yet inventive—was carried out remarkably well, resulting in a genuinely enjoyable film. I found the characters appealing, and it held my attention throughout most of its runtime, even though the quality began to decline around the midpoint. The conclusion wasn't particularly satisfying, but overall it remains an entertaining, original production that’s worth seeing.
