Dino Thunder one of the best

The series has some of the most consistent characters throughout the franchise and their evolution is pretty plain to see. Conner, especially. He isn't the same insensitive, condescending jerk he was in Day of the Dino. Sure, he still says insensitive stuff sometimes, but as explicitly stated many times throughout the series, he's become more aware of it, and he is working on getting better about it. The list of girls was shallow, but he self-corrected, as he was never able or willing to do at the beginning of the series, when he always making excuses to justify his behavior rather than apologizing for it. Hell, his closest friend appears to be Ethan, someone he would have only mocked before the start of the series. He's changed a lot. So have Ethan and Kira.

Character-wise, Dino Thunder has some of the best writing of the franchise, which frankly was always Doug Sloan's strength (Ninja Storm highlights this as well). Funny enough, Tommy wouldn't have had really any consistent character traits in the early seasons if it wasn't for Doug Sloan. The characters fill so real and the chemistry between them was magic, partially due the awesomeness of the actors, but also due to how well they were written. I bought them way more as people than almost every other cast. Dino Thunder is the season I hold all other post-Zordon seasons up against and one of the main reasons I actually prefer Doug Sloan to the legendary Judd Lynn (who I also love). We'd be lucky to have another season like it.
