I have been listening to John now for about 4 years (and I am probably way overdue for writing a review) and the show has never stagnated. John is always in top form displaying a knowledgeable and critcal perspective on the weekly comic books he reads, as well as giving out a heavy handful of recommendations in the previews spotlight. I have always been entertained, and truthfully, I cannot sing enough praise for the show.
My greatest complement for the show would be the respectful and serious nature with which John and his co-hosts handle the material. They treat the medium as the true art-form it is, but they are also aware that different comics hold different purposes; they hold each comic to its own aspirations and then pass judgement.
In other words, John and his co-hosts are very intelligent and eloquent in elucidating their thoughts concerning the material, but they never become snobbish or patronizing.
Great show! Can't wait for more!
(Also, while it was sad to hear Bob go, I have thoroughly enjoyed Drew and Chris Marshall as the new co-hosts. They have been fantastic!)
