Why do people here seem to hate Jack Keroac so much?

I didn't read on the road until my late 20s, but it's beautifully written and he has a unique way of describing simple, mundane things which pulls you in. He's able to sensationalize everything in an entertaining way.

Would I call his literature life changing, or even special? Not really. He's more of a poet than a writer IMO.

However, people on this sub (searching previous posts about him) seem to really look down upon him. Why? Why can't he be accepted simply as he was? While I didn't love any of his books, I do love some of his descriptions (the long melon fields one, which is famous, is beautiful)
