Same here, I don't know if this was my first post-apoc movie, but it's definitely one of the early ones I saw on TV.

Was this the one with the super roaches that could not be stomped on or something?

Yes! I wonder if that's why Mad Max Fury Road was so critically acclaimed even though it had almost no dialogue or story. It was like the Crouching Tiger to all the cheap Kung Fu movies Ang Lee was taking from. Assuming we're still around 20 years from now Fury Road will be remembered by me anyway as the movie with the flaming double guitar dude and this one as the cockroach movie.

the new mad max had too much dialogue and too much love story. also i don't know why the mra pussies went nuts.

you forgot The Garden of the Finzi-Continis

You mean I've been keeping radium in my shorts for nothing all this time?

It's duck pin so it doesn't really matter anyhow.
