It was a great movie, even though the costume was clearly foam rubber. I always got a giggle watching his spikes bend and wobble when he got tossed around. I think the power rangers stole the fight choreography and effects. I thought Mark Hamil had a great role, hilarious death scene.
I think all these were made around the same time period, along with stuff like Krull. It all had similar effects which were just bad enough to be good.
