As a film reviewer for a newspaper, I respect a few critics. Even though I might not agree with them, I acknowledge Ebert and Maltin as two of the greats for the field. As for the newer generation, I consult RedLetterMedia. I agree with everything "Plinkett" argues, but as for the other presenters in "Half in the Bag," I find myself disagreeing with them, or resting on the proverbial fence post. For older films, I consult Brad Jones' reviews.
I used to follow Doug Walker's work consistently, but found his criticism has deteriorated over time, as well as the enjoyment factor of his programs.
