"2-D Blacktop" was a pretty lame season premiere. I liked the math/geometry gags and the workings of the 2D world, but the rest was pretty bad. I gather it was parodying those Fast and Furious
movies, but I've never seen those. I'm not sure it would've worked any better for me if I had.
"Fry and Leela's Big Fling" was a lot better. It was more character-driven rather than just gag-driven like "2-D," but it had some good gags and puns on the simian planet ("Christopher Colobus" -- ha!).
