There are performances where it is debatable, but also some where average pormstars would do a far better job. Hell, there are some where a tree would give more life to the lines

So a twenty minute monologue of backstory is just as skillfull and good as weaving exposition into the script as characters do stuff, with a chunk of it being non-verbal?
So if I spend ten minutes using a piece of composition software (so far in my life I've never touched any), it's going to be just as good as the work of a trained composer played by a skilled orchestra?
People poo-pooing a genre is not the same as giving critical anolysis to a piece of music in the context of of its genre and a need to fit a certain scene; if you compare two symphonies you can pick one out as sounding worse than the other, then dig into music theory to explain why. Also, there can be beautifully written pieces of music which are absolutely horrible for a particular part of a film, due to a mismatch of mood/atmosphere/theme (music theory has this covered, too) leading to a completely disjointed experience that tears you out of it.
I'm not an animator myself and my internet connection is acting up, so I can't give you the technical terminology and my memory is imprecise, but there definitely are things that can be judged with objectivity -- if characters move in a jumpy or stuttery way, or very inconsistent, that simply isn't good (outside of very specific artistic choices). If someone is clearly trying to accurately draw a human, but the proportions and anatomy are bollocked, you can fairly say it's rubbish. Now, it may manage a certain charm, possibly even
because of the poor skills of the artist (I mean, naive art is a thing), but that doesn't magically make it well-painted, it just means it's managed to stumble into having some sort of artistic merit.
If a monkey on a typewriter can't do as good a job as a human, there must be things that do and do not work -- well done and poorly done. People can like things in spite of there flaws, or due to having a particular taste for it, but that doesn't mean the work is equal to another.
There are plenty of people who like drinking Corona, but it is thin (this can be measured with a hydrometer) and has little taste. I can say that Saison Dupont is a much better beer, and the only real argument that could be mounted against the statement is "They're different styles, man"... which ain't so much a counterpoint as a dodge (and not a good one). Now, I'm quite happy for someone to say they don't like Saison Dupont, and even say that they prefer Cornona, but I draw the line at conflating "what they like" with "what is good".
I could use compound chocolate and Lindt to make a similar anology for the teetotallers in our audience.
EDIT: Oh, and it's entirely possible for someone to say, "This is very well made, but I struggled to get through it".
