I'll keep it simple. First four seasons are fun and interesting with lots of stories and twists and aha moments. CMT took over in season 5 and you can instantly feel a difference in the show. Characters are dropped, less focus on the music, poor character development, boring plot lines and a bit of political correctness is thrown in. To sum up. Season 1-4, I would give 9 stars. Season 5-6, 3 stars
