In general, though, tokusatsu was the first live-action Japanese entertainment I watched (unedited-- like everyone else, I'd seen Power Rangers). I found the force and boldness of the writing captivating. This was not a genre afraid of looking silly or being weird, it simply was what it was and screw you if you didn't like it.
Tokusatsu focused on trying to constantly entertain where similar American media becomes self-conscious and hopelessly metatextual. A good tokusatsu will try to entertain you in every minute of every episode using every trick imaginable-- costumes, fight choreography, music, acting, effects, gimmicks, rituals, setpieces, comedy, melodrama, action.
Enthusiasm is to me what separates vital and living art from the pretentious, sterile world of "high" art. Tokusatsu lives and breathes as few other genres ever have or ever will.
