Fine Brothers Entertainment’s Kids React series continues, and this time around, these kids are listening to heavy metal legends Black Sabbath. Previously, we heard these young critics expressing that Led Zeppelin are “really boring,” Avenged Sevenfold’s lyrics make “no sense” and wondering how anyone could understand AC/DC. Now, we get to see if Black Sabbath reaches their standards.

Check out a few of the comments and watch the video below:

“It’s the Iron Man theme song.”

“It sounds like a sith lord!”

“This is something I would listen to.”

“Everyone knows this song.”

“Oh my dad knows that part on the guitar!”

“It sounds like a scary movie song.”
