Critical response

While reviewing the first part of the crossover, Jessica Lerner from TV Fanatic said that the episode "was mostly positive" but that the main call of the week didn't work stating that "While it was clear the show was trying to send the message that we should be adhering to social distancing guidelines and wearing masks, it just felt heavy-handed. It felt more like a public service announcement than something that happened organically and detracted from the rest of the episode in how preachy it felt at times".^[13] Jasmine Blu from TV Fanatic also reviewed the second and third parts of the crossover saying the multiple storylines "made for a mishmash of confusion and too much crammed into the premiere" but also stated that the ending scene "delivered the shock of a lifetime with a fallen Meredith and a Derek sighting!".^[14]

Lincee Ray from Entertainment Weekly said that "the amount of content the Grey's Anatomy showrunners stuffed into two hours proves that they made good use of their time during lockdown".^[15] Reviewing everything as a whole, Maggie Fremont from Vulture said it "pretty much caught us up, even if very quickly, on where every character's drama from last season stands".^[16]
