I picked up a copy of Mighty Morphin Power Rangers: The Movie (SNES) the other day, and had my first taste of it. It's a pretty solid beat 'em up. Fairly difficult, too. I failed to reach the end of the first stage on two credits.
I'm glad to hear you gave this one a play, it's a favorite of mine. In fact it's one of just two SNES carts I own (the other being Run Saber), really wish both of those had SFC releases. It gets a lot easier, trust me, first time I cleared it I was on my last credit, last life, then second play was a 1CC.
