does kerouac “hold up”?

hello!! first of all: to me, yes - I am a big fan. I read On the Road when I was 18 and loved it (but strangely have never reread in full) and since then I’ve always come back to his writing. I am currently reading Vanity of Duluoz and I’m really enjoying it. however, I’ve met MANY people who have tell me that they liked kerouac when they were younger, but definitely not anymore. I’m really curious about how people here feel about him - does his writing “age badly”? please know I mean no disrespect to him, he absolutely is one of my favorite writers ever
