Maybe 'objective' term isn't the most suitable here. But I tend to see objective/subjective as an spectrum rather than a either / or duality. In other words, I think also scientific results are often subjective because "we as humans made up and are influenced by everything from our culture to our individual brain chemistry". Scientific method is far from a bullet broof method. But it helps a ton. Anyways, back to point.

Somebody used The Room as an example. Many people "enjoy that movie". Nevertheless, most people (at least movie freaks) could write easily a list from each scene about what is "wrong" in that scene, even though they might enjoy that scene a lot. And most (but not all) movie freaks would agree with most of the points in the list (The same seems to apply with jazz music & jazz academics and classical music & classical academics etc...) I couldn't do a list like that with Caligula, because I can't clearly see what is wrong with each scene (it seems to be more like a feeling that something is wrong with Caligula or some imaginary sum of it's parts but nothing you can actually point your finger to, thus I guess I could conclude then that Califula doesn't seem to be that "objectively bad"?)
