Club gave the episode an "A−" rating and wrote, "Possibly the smartest decision Grimm made in its first season was the choice to add Bree Turner to its regular cast shortly after her first appearance.
Plus her appealing chemistry with Silas Weir Mitchell took a character who was already the strongest part of the ensemble to a new level, producing both the adorable Monrosalee moments and instances of raw emotion when this partnership is threatened.
"[4] Kathleen Wiedel from TV Fanatic, gave a 3.3 star rating out of 5, stating: "In certain particular ways, 'Lost Boys' definitely felt like a throwback to early-series Grimm.
From the unsubtle fairy tale adaptation to the direct references to Adalind's and Nick's 'first times,' it's almost like the writers were feeling sentimental for vintage Grimm Season 1!
'Lost Boys' was twisted and upsetting and sad with only the faintest glimmer of hope for a world where Wesen, Grimm, and human exist peacefully.
Being stuck in the foster care system sucks even when you aren't secretly half of the villain in a nightmare-fueled fairy tale, as Rosalie's wannabe children reminded us all.
Teetering between creepy and cute, the clueless kids just wanted a mom to love them, but were too maladjusted by a lifetime in the system to realize that you can't just kidnap a woman off the street, tie her up, and call her mother.
"[7] Christine Horton of Den of Geek wrote, "This third episode of the new season of Grimm is, to quite a large degree, a return to the familiar Wesen of the Week storylines that have traditionally been the show's bread and butter.
