What are some good qualities of “bad” games (modern or vintage)?

I think Spider-Man and X-Men Arcades Revenge is pretty bad. The game is really difficult, has limited continues and the X-Men characters aren’t super fleshed out. It’s mostly frustrating to play the slow first level over and over again to get to the main game after each game over. 
 

However, the way they handled Spider-Man as a character was pretty fantastic. He’s got the wall climbing, swinging from webs, spidey sense, they all work quite well and he’s fun to play as. It would be nice if the level design was better to take advantage of the way he controls. 

also the music and visual style are top notch
