I tuned in to the premiere because I'm a fan of Cee-Lo, that was it.
But I stick with because there was some actually good artists competing, and not just "voices" thankfully, mainly Dia Frampton whose cover of Kanye West's Heartless definetly sold me on her talent. Nakia, Vicky and Javier are also bonafide artists.
Add the playful banter/revilary between judges (even if I find Christina annoying), and good production value, and you have the only singing competition that I'd watch.
Bad points being the typical forced dramatization, the total blandness of Carson Daly, and the stupid media/twitter room.
But all in all I'd put it around my favorites reality shows (Top Chef & Survivor).
