[Sentai Tamashii]

I think that you had a good childhood memory, so you are trying hard to recapture that nostalgia, it's not so much of the content that you are watching now that's eluding you, but the environment in which you used to watch the show as a kid. I've never found any of the sentai series (that I've watched) comes even close that feeling of campy-ness that the 90's MMPR captured. I think you are better off watching dubbed series as they come out, enjoy Gokaiger when it becomes Super Megaforce I guess.
