Generally speaking explaining why you dislike something is important so that others know just whether the issue is that something is shit or that you are shit.
Eh. You should be able to just say "I didn't enjoy it" and that should be fine?
By default, people who don't like things do so for entirely innocuous reasons. Including things that have a vocal contingent talking about how it sucked because feminism or political correctness or cultural marxism or whatever; if someone isn't actively complaining about that, or dogwhistling about how they brought ~politics~ into it or something... just assume they didn't like for all the usual reasons people don't like media.
