I've watched the first five episodes so far as of this posting and am quite enjoying it. The story is moving along a little more slowly than in past Tom Clancy onscreen iterations, but that's to be expected over an eight-hour series as compared to the previous theatrical two-hour movies.
For those whose memories of NBC's The Office are still somewhat fresh, you might be forgiven to think at first that it simply features a CIA Jim Halpert. However, John Krasinski does a good job as CIA analyst Jack Ryan, especially when paired up with Wendell Pierce's James Greer.
All in all, I can't wait to complete watching the rest of this season's episodes.
