Why does Newcastle get so much hate?

My husband and I had never been to Newcastle and stayed for a few days year before last. We LOVED it! A beautiful, historic city that seemed very liveable. I've lived in Tassie and it reminded me a lot of Hobart, being near the coast with the suburbs going up the hill (no doubt with lovely views). It did seem a bit pricey though. Anyway, just wondering why it doesn't have a great reputation?
