As with everything, it real boils down to how pushy one is in their criticism.
If somebody who loved the thing goes looking for the opinion of others and finds critical opinions, well, though luck for them - they went looking for it and nobody else posting in what’s a public forum has any moral obligation from refraining to post a negative opinion, IMHO.
If however one is being relentlessy critical mid-film after the other person has made it clear that they don’t want to hear it, that’s being a selfish asshole in my view.
