This series is a pleasantly slow meditation on the torturous creative process, on late-60s/early-70s America, on writing and filmmaking, and on the struggle between the creatives (dreamers) and the accountants -- using the machinations and juicy behind-the-scenes struggles that eventually produced one of the great films of all time as the vehicle for exploring those tensions. I don't know how the writers pulled all of that together in just three episodes (so far), but they have. Beautifully executed. Beautifully filmed. Superbly acted.
