Kinnear was probably the most humiliatingly bad appointment - it was genuinely outwardly embarrassing having him as manager, whereas most of the others were just plain embarrassing. He was an absolutely dreadful manager, only outdone by Carver in terms of ability.
In terms of hatred, I'd put Kinnear second again to Pardew, with Bruce rapidly rising up the ranks. Time has a habit of numbing anger, but it shouldn't be forgotten just how detestable and damaging Pardew was due to how long he spent here pushing Ashley's agenda.
Pardew successfully realigned expectation for a large portion of our fanbase.
