For shear lack of any redeeming qualities, that *honor* would probably go to Last Action Hero for SNES.
It's a side scrolling beat-em-up. The most bare-to-the-bone beat-em-up you could ever imagine. It's like someone once read a description of what a beat-em-up is that was written by someone that's only ever seen screenshots of real beat-em-up and went with that.
Just look it up. It's beyond bad in the worst way.
