“Brooklyn Nine-Nine has really been whiffing on its holiday episodes this season; first it was “Halloween II,” now it’s “Lockdown.” These episodes suffer from the exact same storytelling problems, both superficial and fundamental. Neither manage to outdo their predecessors from yesteryear, but in all honesty that’s not a huge issue—if either managed to just be solid in their own right, nobody would bother making unfavorable comparisons to their 2013 counterparts. No, the real dilemma here is that “Lockdown,” like “Halloween II,” stubbornly refuses to advance its story or develop its characters. Instead, the narrative spins its wheels for fifteen minutes, and only accords actual growth to the five leftover.” – Via Paste Magazine
