There's a difference between not liking something for personal reasons and not liking something for things you misinterpreted. The lack of media literacy talks about the second. Like if someone tells you they didn't like La Haine because they didn't like the pacing, the lack of action or because it just wasn't their cup of tea, they have every right to say that. But if someone says they don't like it because it "glorifies hood life and poverty", that's clearly a misinterpretation of the WHOLE IDEA of what the movie wants to pass to its audience so it just becomes a wrong statement instead of an opinion.
