If you think cartoons aren't a very deadly serious subject, you will be stunned by the sheer intellectual and existential gravity of Uncle Eddie's Theory Corner, hosted by former Ren and Stimpy/Mighty Mouse animator Eddie Fitzgerald (he also worked on Animaniacs but we'll forgive him). Perhaps nobody since Chuck Jones has been able to speak so seriously about funny cartoons. In fact, it's hard to imagine how a man so adult and mature could possibly make a living creating silly funnies for the kiddies.
If you like your cartoon commentary dry, humorless and severely intellectual, then Uncle Eddie's Theory Corner is the blog for you. Hats off to Uncle Eddie!
