Oh, man. A talk about one of my favorite nostalgic shows. High school kept me away from the series, even though I had a number of friends who enjoyed it as much as I did.
If I have to list favorites, that's pretty tough. There's a good number of aspects and characters I've enjoyed most thoughout all 18 seasons. Still...
Favorite Season - Mystic Force, followed by Lightspeed Rescue. I've enjoyed Mystic Force more than most other seasons, despite the issue of the show and plot placing a lot of focus on a few characters rather than the whole team. I think the idea of medieval, magic-using Rangers was what drew me into this one.
Favorite Character - Jennifer "Jen" Scotts from Time Force. Aside from the fact that she's one of the tougher and more commanding pink rangers, and the one I recall with the best character arc that I've seen thus far, I have to commend her actor Erin Cahill for something else which makes her my favorite ranger. She is, to my knowledge, the only American ranger to tweet to the children of Japan through the Sentai tweet network as her ranger character.
Favorite Villain - Mesogog from Dino Thunder. A half-dinosaur Jekyl and Hyde character who believed in the superiority of dinosaurs over humans. He was also instumental in a few sub-plots for the white and black rangers that season. Sure, Zed and Rita were and always will be great as villains, but Mesogog beats both of them hands-down.
Favorite Moment - Seeing Bulk again in PR: Samurai. Let's face it, Bulk was a great foil back in the day. While Schrier is no Curly Howard, he still has his goofy side in top shape even 18 years later; most of the slapstick with he and Spike in Samurai is worth a chuckle.
As for the future of the series, I have to wonder how Saban is going to do Goseiger and Gokaiger. The former is relativly simple since it's an angel and card motiv for the series, but Gokaiger? Well...
If Saban can find some way to make this scene, let alone the whole concept, work for a Power Rangers season of Gokaiger, I will be VERY inpressed.
