Tokusatsu is basically a genre of japanese media that relies heavily on special effects, and deal primarily with horror, fantasy, and/or sci-fi stories. Things that would fit this criteria are Godzilla (part of the "kaiju" subgenre of tokusatsu) and Kamen Rider (part of the "sentai/superhero" subgenre of of tokusatsu); about that last one, the Power Rangers series is basically footage/costumes/props/etc from a "Super Sentai" series mixed with different actors, setting, plot, music, and what else have you, basically creating a different show altogether. Just a fun fact.
From what I've personally experienced of the genre, most tokusatsu movies (especially older ones) aren't really "good" in a conventional sense; they're campy, enjoyably bad, a guilty pleasure, and occasionally nostalgic. Somehow, the finished product manages to evoke a unique charm and keeps you entertained even though it's supposedly a "lower" form of entertainment. So that's something you have to be prepared for when watching one.
That said, has anyone here actually seen any tokusatsu (btw PR doesn't count) ? I've watched numerous Godzilla films, and right now I'm up to episode 13 of Kamen Rider Black. Formula was starting to get kinda stale up until episode 11, it seems to be picking up now. Wonder when Shadow Moon is supposed to show up, as I assume that's when the show will really get interesting.
