What bothers me most about Hurwitz is not his variety of biases - he's entitled of those and he doesn't make a secret of it - but his general music philosophy.
To him, music equals entertainment. He admitted that in a recent video. That explains his preference for colorfully orchestrated scores, for spectacular recordings and for technically immaculate playing - all factors that contribute to the entertainment value of music. This judgement extends to music genres that offer - or strive to offer - more than just entertainment. For instance religious music, highly philosophical works, pieces with difficult literary content, etc. Those values are just distractions to him that get in the way of his enjoyment.
According to him, the St. Matthew's Passion has a worthless story, Parsifal is ridiculous (but the music is oh so beautiful!) - and performances of music that seeks to bring out other values than just superficial pleasure are mostly mistrusted, specially in cases where there's a compromise between outward technical perfection and spiritual content. If a performance leans towards the latter, emphasizes a composition's spiritual content and shows some neglect of technical precision, it's rubbish to him. His betes noires: Furtwängler, Barbirolli and Horenstein (don't be fooled by his positive review of the Barbirolli Elgar edition - he only praises the non-Hallé recordings, showing that he doesn't understand what makes Barbirolli a great conductor at all).
Hurwitz is a one-sided and narrow-minded reviewer lost in a universe that has so much more to offer than just technical perfection and superficial entertainment.
