"Plumed Serpent" received positive reviews. The A.V. Club's Kevin McFarland gave the episode a "B-" grade and wrote, "In all fairness, I'm surprised that Grimm made it all the way through thirteen episodes without having someone kidnap Juliette and forcing Nick to save her. The prince saving kidnapped princess storyline was an obvious one in light of the fairy tale genre, but even in a universe that accepted any and all types of creature, dragons are a tough one to weave in. As Grimm went to commercial with about fifteen minutes left, I predicted that Nick would set off for Juliette with Eddie in tow, and that Eddie would bring up just how classical the setup had become, and lo and behold, that’s exactly what happened. Eddie has a few nice quips about Nick being the Prince, dragons kidnapping his princess, and needing to slay said dragon and rescue Juliette in order to fulfill some classical honorific story."[3]

Nick McHatton from TV Fanatic, gave a 4.4 star rating out of 5, stating: "'Plumed Serpent' was easily one of the most imaginative episodes of Grimm yet. We all give Once Upon A Time a lot of credit for bringing fairy tales and Disney to life, but Grimm should be given its fair share, as well, for delivering its own unique style and spin on things. How the show is shot, and finding the whimsical in and around Portland, can't be easy to do every week. And that's before they bring it all together as a modern day fairy tale. Plus, who doesn't like epic lairs? Those always get a little bit of extra credit from me. My biggest gripe with Grimm continues to be the lack of Eddie. It's hard to like Hank at all when there's a much better alternative out there for Nick. Honestly, did Hank serve any kind of useful purpose this week?"[4]
