"Star-Crossed" received positive reviews. Les Chappell from The A.V. Club gave the episode a "B+" rating and wrote, "The uneasiness of that status quo is on full display in 'Star-Crossed,' which takes a familiar move out of the show's playbook—barbaric Wesen ritual in modern times — and updates its import by tying it to the season's unrest. The end result is a case of the week that's more interesting than that usual format, helping to spell out on a micro level the changes in the show’s ecosystem. While Black Claw's engaged in many acts of rebellion around the globe, 'Star-Crossed' understands that the group's reach is far more insidious than outright declarations of war, and that its promise of dominance can spark a thousand fires."[4]
Kathleen Wiedel from TV Fanatic, gave a 3.7 star rating out of 5, stating: "Older does not mean better. Someone really should remind Black Claw of this little piece of advice. In Grimm Season 5 Episode 9, one of the Black Claw disciples decided it was a grand idea to ritualistically kill a number of humans in order to end a drought. Nice. While one can't automatically discount the power of the ritual, surely there must have been a less bloody way to call rain?"[5]
Lindi Smith from EW wrote, "The case of the week on 'Star-Crossed' involves bodies being strung up on crosses with glass shards over their eyes around the city in ritualistic fashion. The victims are all homeless men and are all found gored to death with a circle of blood around them on the ground. On each of the crosses is a different ancient rune having to do with the element of water. Coincidentally, the area is experiencing a drought."[6]
MaryAnn Sleasman from TV.com, wrote, "With 'Star-Crossed,' Grimm finally captured some of the depth that it's been seeking but failing to grasp this season. Generational divides and the allure of extremist ideologies fueled Portland's latest Wesen homicide and the threat that Black Claw represented became something more relatable than a vast evil underground dedicated to evildoing. Sure, Grimm took the easy road by essentially making them Nazi Wesen, but hey, everybody loves to hate Nazis. They're the only villain you never have to justify hating. They incorporated skulls and crossbones into their uniforms, for frick's sake! That's laughably evil even for cartoon evildoers, but no one is laughing at 6 million murders, and with all of its insidious propagating to impressionable young Wesen and their angry, disenfranchised elders, Black Claw was methodic in its madness. Sadly enough — just like in the real world—there were ears who wanted in on the crazy they were peddling."[7]
Christine Horton of Den of Geek wrote, "Grimm's fifth season continued its descent into darker territory this week. Alongside a behind-the-scenes glimpse into how Hadrian's Wall operates, a Wesen storyline that fits well into the show's main story arc and a potential jab at modern politics, we were also witness to some previously unseen levels of horror."[8]
