Personaly, I've always and probably will always have a huge fondness for Kobayashi and her work. Gingaman and Timeranger are two of my personal fave Sentai seasons, Ryuki was almost brilliant until episode 30 or so, PGSM was suprisingly really well-done and I know everyone despises the show but I loved each moment of Den-o and it's wacky comedy.
Shinkenger was a bit of a downer but it was still a well-done season for the most part. the characters stood out and the action was really well-done, better then alot of other sentais have been. I have no inclination about how OOO is going to be like so I'm just going to wait and see. Honestly though, if it turns out to be fantastic, I'm going to do an "I told you so" dance. just fair warning okay?
