The problem is that these levels get fairly repetitive, and longer and longer as you go on. Yet for myself, they provided some of the most amount of fun in the game. Superman controls best in air, and despite superman having this awkward car like feeling, once you get adjusted to the controls, you will find yourself blasting through the levels. Now one problem remains, why in the hell is superman flying through rings?
The ring levels feel like padding for what I consider the true Superman 64: The action levels. These levels seem closer to what you would expect out of a Superman game; having many cameos from the animated series villains. The levels felt ambitious, having multiple objectives and tons of enemies to tear through, yet there is never a satisfying level of polish.
The game tends to get fairly bugger at this point. I must of feel through the god damn floor so many times. I did want to punch the screen when I had to restart the last level 3 times becomes characters wouldn't do what they were suppose to. Superman 64 was at least able to remind me during these levels why people hate this bloody game so much. Though in the game's defense, the action levels were fairly short, and even the ring levels helped you out when you did bad.

Even with it's flaws, I suggest to try out the game before jumping on the hate wagon. You might be surprised at what you might find... mostly shit, but come on, I'm trying to be as positive as I can.
Pros
+ Ring levels can become fun if you forget it's suppose to be a game about Superman
+ Game is forgiving and rewards players for continuous effort.
+ Decent adaptation of the Animated series
Cons
- Ring levels become fairly repetitive later on, as the same concepts repeat
- Controls are awkward and take a while to get use to
- Bugs will mean you will play some levels a lot
- Poor Production value
