Agreed with you, fellow Praetor. (Times like this make me wish I'd stayed Praetor Neral. Almost.)
Go-Busters was horrifically boring and I nearly stopped watching partway through. Hiroya Matsumoto's Gold was all that kept me in. Part of the charm of super sentai is the campiness. The Kyoryuger characters are bigger than life and easily likeable.
I think one explanation for that was that all of the main six are written in the mold of the hero protagonist.
