This season did Sam dirty.
This season was... a bit boring, and less visually appealing. The Red Dragon was probably the worst villain in the show. But it was alright, and it was good enough to be worth watching!
This season has a bit more of a confusing plot / red thread, but it works out fine by the end where you'll catch up if you fall out. It is an incredibly amazing season, with a strong beginning and a strong end.
New, innovative and smart. I loved how the story progressed and how the season ended. An overall great season.
