My real intention here is to get other podcast recommendations, but I have some thoughts on this. Here's what makes Bald Move so good (as far as I can tell).
1. Intelligence: this one is simple. Jim and Aron are just generally smart and insightful dudes.
2. Focus: Jim and Aron stay on task. They get to the point. They rarely (if ever) chase rabbit trails. And, even though they are both very funny, they don't chase jokes. They aren't trying to be funny, they just are funny. They leave jokes where they need to be (and don't belabor the point).
3. Homework: yes, Jim and Aron are intelligent and insightful... but they make good use of the intelligence and insights of other people. They seek out the best perspectives that can be found on the internet. Of course, importantly, they don't just leave it at that. They build on / evaluate those other perspectives.
4. Chemistry: Jim and Aron are a great pairing. Yes, Aron may have more of the "gift of gab" than Jim, but gabbing alone only makes for a pretty-good podcast. Every Aron needs a Jim (and vice versa). Jim has plenty to say too, but his natural state seems to be to sit back and critically evaluate what he's being pitched... he consistently challenges ideas, clarifies questions, etc.
Have I missed anything (and)?
Are there any other movie / tv podcasters that hit all these points? It's my experience that most miss on at least one or two of these.
and 4 others.
