I only really named Megaranger because the question didn't leave me much room, honestly.

I found Jetman's dynamic to be too intrusive. The love quadrangle got grating and it felt like the characters were too oblivious (And Gai's declaration of love to Kaori's face and then her proceeding to just string him was awful). Gai loved Kaori, Kaori loved Ryu, Ryu can't get over Maria, and Raita randomly loved Kaori, too, but they bring it up a whopping two times before it becomes irrelevant. The problem was that they basically made the characters' stories revolve around one of the most dull characters in the franchise. Kaori is such a vapid stepford smiler whose barely has anything interesting going for her.

The villain dynamic was more interesting, but it was wasted, since once Tranza got into power, it was just a giant downfall from there. I enjoyed all 4 of them, but Grey didn't do much until his end and Maria felt like set dressing. Radiguet and Tranza were the best of the two (Radiguet more so). But Radiguet didn't really get interesting until his brief time as a human and Tranza was just more of a mover, rather than an interesting character.
