For sitting on it's ass until the end of the first season with random fillers which were actually remakes of old random fillers before actually getting a kick in the pants with "council" of evil" on, it was only half good.
I`ve read interviews from the original creators that they wanted to do an actual story with the show instead of "He-man saves village X from skeletor, Iteration 23. Skeletor gets away, everyone laughs and learns a moral". Mattel hit them with rediculous constraints such as not being able to kill/send off useless charachters or give new people proper introductions. Heck, the VA of She-Ra was constrained from ever using her "she-Ra" voice for any other production EVER.
So, this begs the question of why did they waste so much time in season 1 after the excellent intrduction movie doing random crap that barely affected the story at all? the answer: Nostalgia. Nostalgia kills.
The series need to be reinvented, with NODS to the original series, not a blow by blow remake like He-Man MOTU 2002. Heck, skeletor calling himself "Overlord of E-ville" probably drew away a lot of people. What villain, other than demons, think they are evil themselves?
Season 2/ end of season 1 was great, and showed the true potential of what a reinvention is supposed to be, but ratings wise, it was too little, too late.
