It's hard to explain, but the mid 2010's production is really bothering me here. It was an awful era for pop music and the hits on here really feel like a letdown compared to 21. I found the songs that dialed the production back a lot better, such as Million Years Ago. The overall sad tone of the album combined with Adele's voice that can get a bit overwhelming to listen to for 50 minutes makes it a dreary sit through for me. There's a few nice deep cuts here though.
