I have always loved the works of Koichi Sakamoto. I know him best from his work on Power Rangers, it was nice to see some of his signature recurring stuff in Kamen Rider Fourze, but without the ridiculous restrictions he had to work with under Disney (all the explosions that everyone complained about from Dino Thunder through RPM? That was because Disney didn't like that people were hitting each other. Yeah...)
He tended to overdo wire work during that same period, but there were times where it really worked, like the Jungle Fury season, which, based on GekiRanger and the Kung Fu theme, was just tailor made for wire work based on the (admittedly few, but mostly Jet Li) Kung Fu movies I had seen.
I truly believe his magnum opus, as far as Power Rangers fights go was in Jungle Fury's penultimate episode Path Of The Righteous with the one on one battle between Casey and Dai Shi.
It's just a real shame he all but gave up during RPM in favor of the Michael Bay on Speed "camera shakes non stop so you can't focus on anything" style.
