To a lot of people something like Antonioni IS fun and the latest mass produced comic book sequel is difficult to sit though. Meyer and Corman have their defenders amonst serious critics. ‘The Immoral Mister Tease’ is something of a classic as are Corman’s best Poe adaptations.
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”.
