Honestly even after all these years and having watched a lot of "classic" films/TV, I still catch some references in early (90s) Simpsons that I either hadn't noticed before or was too young at the time I first watched it to appreciate. Don't feel bad about it.

It can be quite fun actually. I imagine a lot of the references in the newer seasons would be lost on me because I've just lost interest in The Simpsons in general. I'm not even sure if the show even does that stuff to the same level anymore.
