Have watched the first two and like so many, have really learned a lot. Ken Burns finds the little interesting tidbits that school history never taught us....I'm enjoying this series emmensely, but will probably relegate it to weekend watching since I'm now into a lot of the new "Pilot" programming. I've found if I don't watch the first in a series that I'm lost if I decide to keep watching it....and it generally takes me two or three episodes for me to decide if I like it or not......I have the Roosevelt series recorded so I can watch it at my leisure. With each episode lasting two hours, it does take a while.
