Sounds like some classic elitism. If you don't like it, it is because you don't get it or didn't finish it. Even though you likely didn't finish it because you didn't like it. You see this kind of thing in a lot of different mediums.
Right? If you genuinely enjoyed it, hey, that's great. Not every book is for everyone. Have at it. Everybody's got different tastes.
But to go up there on a pedestal and mark it as one of the great literary achievements of the past 400 years and anybody who disagrees otherwise is a rube...Come on now.
