The film’s Rotten Tomatoes score opened at a perfect 100% from a small batch of UK reviews following its March 27 theatrical debut, then settled into the mid-80s (86% of 37 critics per recent aggregator data) as more notices arrived. Critics have praised its warm, whimsical tone, strong performances from Andrew Garfield and Claire Foy, and timely “unplugging” message, while noting uneven pacing, overfamiliar plotting, and mixed child-actor results. With the U.S. wide release set for August 21, additional reviews could nudge the final certified score, though the current consensus already reflects a charming but unexceptional family fantasy rather than a breakout critical hit.
