Ah, the internet. Where a 22-year-old box of cereal is sold at auction on one website (eBay), and reviewed on another (FoodJunk). And how did this 3D-ish box of Batman cereal fare? Let's hear from the critics:

I was hoping for some kind of honey nut aroma remnants upon opening the bag. Sadly, the villain in this issue is The Plastic. He has taken over virtually all of Gotham. The thick plastic inner bag held up perfectly (take that Earth!) and did a great job of keeping the cereal dry and crisp, but the air inside was thick with chemicals. And not the kind that would put a cool maniacal smile on your face.

The Plastic co-opted the cereal’s taste as well. It laid waste to all of the little yellow multigrain bat symbols.

You can taste the sweetness, but the original honey nut flavor is barely recognizable. It’s there, but it’s not worth diving into this vat of toxins to get to. The plastic tang is quite powerful and lingered in my mouth for quite a while until I was able to defeat it with a little help from the always helpful sidekick, A Spoonful of Peanut Butter (Jif Wonder?).

I added a little milk and things only got worse. Giving The Plastic a liquid assault vehicle with which to wreak havoc was a bad idea. It sort of felt like suckling on the end of a caulking gun. I stopped after a few bites, as I was convinced I could feel the bat days being torn from the end of my bat life.

Well 1989 was a long time ago. Batman still holds up as a great movie. As a cereal, not so much.
