I watched every episode. There's clearly an LGBT agenda going on the show. The character designs are poor. Also the lack of masculinity in the show (Bow being a prime example).
Season 1 - Slow starter. Actions scenes not well done. Gets better as it goes along.
Season 2 - Is decent. The action is a lot better. There's genuine growth as the princesses and Bo have become better warriors and tacticians. Better than the first season, overall.
Season 3 - Better than the previous seasons. I like the relationship between Entrapta and Hordak. Also, like Hordak's back story. The season shows that there are high stakes for failure and sacrifices are necessary (won't go into more detail but someone dies).
Season 4 - The best season. Double crosses. Corrupting influences. Twists and turns. Character growth. Introduction of the true Big Bad, Horde Prime.
Season 5 - ...
They done fukked it up. A straight up contradictory mess. The constant whining of certain characters. Many characters became annoying. The only redeeming part of the season was Hordak Prime. He made the season bearable.
