Whether the literature side is interesting or not depends a lot on the teacher imo. One of my teachers didn't even read the book she was supposed to be teaching us, and then docked everyone marks in the mock because what we wrote didn't agree with an online study guide she'd found people complained to the head of department (who had actually read the book) and he was basically like "yep, you're all right but I'm not supposed to micromanage her marking".
That teacher then left later in the year and we got a different teacher who had done a master's in French literature and suddenly I loved literature. She really made us think and taught us so much without spoonfeeding.
I did the old specification, which included lots of "controversial topics" (abortion, death penalty, nuclear power, basically anything you can think of) and debating, which I loved. I don't know what the new spec is like though.
I think I learnt more French in two years of a level than I had in the whole of ks3-4. I'm not fluent but I can read books and newspapers, listen to podcasts, and talk about loads of things - I even managed to give a statement to the French police entirely in French
