I could never get into Bionic Commando cause I was always too tempted to jump.
But while I probably would prefer the remake (or the 3D game that came out the same year, if I'm not mistaken) I don't think NES graphics are crappy. I think that was probably the first era of home consoles where there was a distinct style that looked pretty good. Why else would games like Celeste and Shovel Knight try emulating that style to some extent (albeit with much better hardware and fewer limitations on graphics).
Now, Atari or Commodore 64? Those games look outdated to me, but maybe this is all just an age question. Maybe those look fine if you grew up with them, like NES games look fine to me.
