Just finished watching episodes 3 through 5 and I enjoyed it. Yes. it's slow and the plot is complex,but the interweave of the characters is what makes it interesting. I'm hooked.
BTW, heard today that Speilberg recently returned from a trip to Cuba, where he had a 7-hour meeting with Castro. He says this was the most important seven hours of his life. That's it for me. No more Speilberg. What an ass.
