Is E.H. Gombrich credible?

I’m on an art course atm and am completing my final project. Within the research I quote Gombrich and refer to some of his theories and references. My tutor HATES him. This is the third time now shes had a rant about him being sexist and old and irrelevant. I used him last year in my EPQ and got an A and have read his work for years now with no criticism from past teachers. Is she right or nuts?
