Strange Planet received positive reviews from critics. The review aggregator website Rotten Tomatoes reported an 82% approval rating with an average rating of 5.9/10 based on 28 critic reviews. The website's critics consensus reads, "Leveraging its alien conceit to make astute observations about society, Strange Planet is wryly amusing and relatably human."[4] Alan Sepinwall of Rolling Stone praised the show for its "reliable level of sweetness", while noting that most of its humor "hits the level of wry amusement and not much more, not unlike the experience of reading a comic strip, smiling, and saying, 'I get it,' without actually laughing."[5] Lucy Mangan of The Guardian gave the show 3 stars out of 5, opining that the comic strip's premise wore too thin during a season of ten 25-minute episodes.[6] In a more mixed review, Maya Phillips of The New York Times found the show's comedic moments to be more uneven and less interesting than its philosophical musings, writing, "More often than not, 'Strange Planet' is cute and delightful".[7]
