This seems to happen to a lot of shows that get dumped all at once onto services like Hulu/Netflix/Amazon. First season generates tons of buzz, people demand another season and then you barely hear a peep when season 2 hits. Everyone loved Dead To Me and talked about it last year and I haven't heard much of anything about season 2.
There are a lot of shows that you dont hear that much about here that are popular enough to get renewals. Dead to Me has been one of the Top daily watched shows on Netfllix since its release.
