I finished watching Season 4 (about time) and I really liked it. If I could point to a non fan the season in which the show started improving, I’d point to this one. The key arc was a very interesting story arc, a lot of the episodes I really liked, and the bad stuff was just more below average than terrible. Also, this was when Hasbro started showing love for the fandom by putting in the stuff that the fanbase likes as a love letter to them. Alas, this was as the season after the golden age has come to an end, which is a damn shame really. Regardless, I loved this season a lot and I call it my second favorite season of the show.
