Laura Frances of Screen Crave gave the episode an 8.5 out of 10, saying "Despite the cheesy scenes between Puck and Quinn, and Santana and Brittany, '100' was filled with great performances, sass and warmth. It was great to see the former Glee kids back singing and dancing and bickering. However, this also reminds us of how great Glee use to be. That's not necessarily a good thing."
