[Dr Kain]

I'm the opposite. I thought Dai had some of the best character development for the rangers. Everyone had their own subplots that developed who they were. The reason Daigo had the most development though is because his sub arc started in episode 9 while everyone else's really kicked off in the late teens and early 20s. Even Kaku (my 2nd favorite) failed at developing Saito and Seizo. Another thing I love about Dai is how little filler there is and I believe it has the lowest number of actual Monsters of the Week in it.

Oh's first 8 episodes are great, but then it starts to throw in a lot of forced comedy afterwards that just does not fit. The show still has a lot of great moments, but the ranger cast is quite generic and it gets really boring. However, episode 32 is one of the best episodes in the series.
