I haven't watched many episodes but they are interesting in that they present intriguing, in depth views and analysis on different aspects of topics. I actually watched this episode on Vlade Divac and Drazden Petrovic for my World Political Geography class. It explained nicely the underlying tensions in the Balkans regions during the mid 90s as well as the story of these two basketball players.
Based on Catching Hell and what I've read about the other 30 for 30 specials, the strength of them is that they talk about the stories on a very human level; the sports aspect is the way in to the subject, but part of the point in watching is to get outside the lines a little bit, so to speak. Thanks for the suggestion. I'll have to add that one to my list.
