This is about as good as you'd expect; It's an extra-long episode of Robot Chicken focusing on DC comics.
Some of the jokes are pretty funny like the "Actually DC Character" bit. That gave me a hardy nose breath.
Unfortunately, the main through-line is just a constant rag in Aquaman. As an Aquaman fan, it's kind of annoying to see such overused jokes again and again, but Robot Chicken was one of the shows that make hating Aquaman so popular so I can forgive it a bit.
