Lost points because of my inability to engage with a boring art film in film class, now the prof thinks I'm immature and he's not wrong exactly

The prof doesn't have ADHD. The prof doesn't know the pain of sitting through something horribly boring and being forced to pay attention for two hours straight. The prof only saw in my film review homework that I couldn't finish the homework film because of how boring it was, and all I really had to say about the film (and its genre) was how dull it was and why I did not think the genre worked, or at the very least why I hated it. And the natural conclusion one might reach, of course, is that I'm childish and immature. This wasn't stated in the feedback outright, but I can see the prof THINKING it, telling me to make a better effort to engage with the material. 7/10 scoring, but with that feedback I feel lucky I got 7/10 at all.

I'd better increase my patience yesterday, because the prof is right to grade me like that -I may have ADHD but that's not an excuse for being unable to handle boring class material. Here's hoping the rest of the film genres are better than Italian Neorealism; I personally quite liked Russian films.
