Why don’t we like Jim and Pam?

I’ve been rewatching the office and scrolling through this community on reddit recently and I’ve seen so much hate targeted towards Jim and Pam, I need to understand why because even though I never particularly loved those two, I never understood the hate towards those two. And especially because I thought jim was one of the most loved characters a while ago.

I know they did do some bad things but I feel like that’s everyone in the office, anyways please comment reasons or things they did that made you dislike them, I’m genuinely curious.
