Yes there are outliers among people, no statement applies to all, but they don’t change the simple truth of what I’m saying. There are arthouse movies, and there are fun popcorn flicks, and most critics love the former and hate the later and one of the things that set Ebert apart was willingness to love the later very publicly. He understood what made a good popcorn flick and was willing to stand up and say “yeah it’s kind of dumb, but I had a really good time”.
If something is truly enjoyable and fun then it has some de facto artistic merit.
