Netflix has trained plenty of viewers to treat freshman shows like mayflies. Fall in love too fast, and there is always a decent chance the streamer will swat the thing before Season 2. The streamer's reputation for canceling so many shows after the first season makes it notable when a returning series not only survives the first-season danger zone but also comes back with better numbers and a fan base that seems louder than before. That appears to be what is happening with the second season of A Good Girl’s Guide to Murder.
Since hitting the 2026 TV schedule, Netflix's Emma Myers-led mystery series currently sits at a 90% Tomatometer score from 10 critics and a 96% Popcornmeter score from more than 250 audience ratings on Rotten Tomatoes for Season 2. The show’s overall Rotten Tomatoes page lists Season 1 at 83%, indicating the returning season has improved its critical score, at least based on the reviews counted so far.
