Well I learned a lot about Putin, his world view, how he viewed events like the Arab Spring, other democracy movements and Russian history. Starts with the resignation of Yeltsin. If you missed it it's worth seeing if it will be rebroadcast late at night or something. Second half will be aired next week. Title is "Putin's Revenge". Lots of interviews with participants and first hand accounts of what was happening. No politics or bias as far as I could tell. Just historical facts and assumption of Putin's paranoia and determination to hold on to power based on historical facts and incidents.
I have always felt Frontline is one of the most informative, unbiased shows out there. Lasts nights program was good, looking forward to the next one.
