Does anybody else not like when the Red is the least experienced/trained member of the group? For example, they pick up a random kid in Timeranger, and Megaranger's red is because he's good at a video game, while the other members are actually smart.

Well, for Timered they had no other choice since they needed five to activate their powers. Plus he was a karate expert so what he lacked in knowledge of the tech he was given he did make up for it with combat. But inexperienced reds overall I do not mind unless they pump them out show after show.

No, actually, they were all picked for being good at the game. MegaPink was also not quite the brightest. There was a complete episode dedicated to her suddenly turning into a genious. ;)

How long super sentai will last ?

As long as it makes money.

Which was your favorite super sentai vs movie just the series vs series.

I think it will last as long as Toei stays in the black with the show. They dip in the red for two or three straight seasons, then it will be cancelled or get a ten year break like KR did.

Shinkenger VS Go-Onger was good and so were Abaranger VS Dekaranger and Megaranger VS Carranger

Megaranger vs Carranger
Timeranger vs GogoV
Shinkenger vs Go-onger
Go-busters vs Gokaiger
ToQGer vs Kyoryuger

Goseiger vs. Shinkenger, Toqger vs. Kyoryuger, Kyoryuger vs. Go-Busters

These.
