Whoo! That used to be one of my favourite programs. I'd get up real early on a Saturday morning just to watch it.
I saw most of the film as well.
What was that disembodied head all about? And some weird kind of log like thing that the head called a body...the fights at the end were the best! Always some giant Sea-monster type thingy against the Robot! When it was knocked down I always thought "Oh no! They're gonna die!" Then they jumped back up again and saved the day, and I cheered! Yay!
I wonder what the Emo Rangers would have as a Robot. And what big monster they'd fight...
