The website's critics consensus reads, "Amiable and cleverly constructed, Extraordinary grounds the fantastical and makes it all the more accessible and thrilling as a result.

"[22] Keith Watson of Metro gave Extraordinary a grade of 4 out of 5 stars, saying, "Every once in a while there's a superpower show that promises to breathe fresh life into the over-exploited arena and Emma Moran's fresh comedy Extraordinary, which slyly exploits the genre in much the manner of The Boys (with way less budget), stands out from the crowd.

"[23] Polly Conway of Common Sense Media gave Extraordinary a grade of 4 out of 5 stars, describing it as an "amusing teen comedy".
