Why do people hate 4e

Hi, I was just asking this question on curiosity and I didn’t know if I should label this as a question or discussion. But as someone who’s only ever played fifth edition and has recently considered getting 3.5. I was curious as to why everyone tells me the steer clear fourth edition like what specifically makes it bad. This was just a piece of curiosity for me. If any of you can answer this It’d be greatly appreciated
