I admire Mystic Force for putting in a slight bit of Lord of the Rings into the mix that Magiranger never really had with the inhabitants in the forest. I also love the idea of having the two Wolf Knights eventually duke it out, because I've always wanted to see the Red Ranger be next in line to get the cursed armour treatment.
Otherwise, Mystic Force in my opinion, honestly feels like Disney gave them a bombshell sometime after production began at earnest and told them to shave the scripts down by 6 episodes when the production team was already pacing the series with 38 episodes in mind. As a result, most of the Ten Terrors arc is like a rushed translation job, and a disappointing lead-on from the Imperious arc which demonstrated plenty of potential. Making Imperious even more of a slimy bastard than Meemy who would even kill his master? That was actually interesting!
Though I still have no idea what the hell Leelee was supposed to accomplish. And what kind of drugs she was on at the end.
