Critical reviews

"The Other Side" received mixed reviews. The A.V. Club's Kevin McFarland gave the episode a "C+" grade and wrote, "Early in its run, Grimm used its epigraphs as a way to introduce whatever fairy tale was the topic of the episode's major plot. As the show progressed, the epigraphs became indicative of some thematic resonance between a tale and an episode. Now, the writer's seem to be combing any and all fairy tale-adjacent material for quotes to fit a plot that never sprang from the Grimm tales themselves. I understand why the source material can be limiting, but the writers have shown a range of literary influences. Episodes that contrast strong in-show mythology with a scramble to tie in fairy tale elements shows how over-complication of this world may not be playing to Grimm's advantage."^[4]

Emily Rome of EW wrote, "This episode, called 'The Other Side,' was not without some forward momentum for the continuing stories of Juliette and Renard's potion-induced obsession with each other and of Adalind's return. Once the show established the group of ill-fated academic decathlon kids, it moved on to Nick and Juliette getting ready for a dinner in Renard's honor – he received an award for his work with the Portland Police. A thank you from Nick to Juliette for accompanying him to a dinner he hopes isn't too dull is met with Juliette's response of, 'Of course. This is what couples do – they go to each other's boring work functions.'"^[5]

Nick McHatton from TV Fanatic gave a 4.0 star rating out of 5, stating: "'The Other Side' sets its procedural story up as one large metaphor for the upcoming drama that is about to unfold. I just wish the killer kid story hadn't been used back-to-back. Thankfully, Pierce being the culprit isn't the main takeaway from the story – it's his genetics. Pierce is half Lowen, half Genio Innocuo, and, because of that, if he can't keep his emotions in check his violent side comes out. It's a light twist to what Renard is going through."^[6]

Shilo Adams from TV Overmind, wrote: "In the world of Grimm, knowledge is the type of leverage needed to survive. Nick had to learn quickly about the Wesen world in order to become a better Grimm, Hank's reaction to the news that Nick can see creatures as well was one of comfort, and Juliette has been trying to get her memory back in order to fully love her partner once again. With Monroe having to pick up information at the spice shop in Rosalee's absence, Renard continuing to obsess over Juliette with no end in sight, and Adalind attempting to get in good with the royal family to get vengeance for her mother, knowledge played a big part in 'The Other Side'."^[7]

Josie Campbell from TV.com wrote, "Up until the ending, 'The Other Side' was a great Wesen-of-the-week episode that did a nice job of balancing Adalind's plotting and mythology with cop-procedural action. It was fun to see Monroe geek out about the spice shop and Hank get upset about the Grimms' bloody past. Plus Renard is such a strong character that I even liked the Juliette storyline. But Nick and Hank's cynical shrugging-off of a mentally unbalanced kid who desperately needed help not only felt out of character for both of them, it also destroyed the whole premise of Grimm — that Nick, despite being a Grimm, is still a good guy."^[8]
