I like The Core but omg it’s objectively terrible. “Unobtanium” is just a buckyball. The random kid drawing in the notebook just for heartstrings. Them welding power connectors right next to each other on the hull so that even IF their nonsense theory was correct they’d only be 0.01% efficient. Oh, and if the core stopped spinning it wouldn’t get the planet roasted anyway.

But hey, it’s a B movie so I give it some slack.
