Band of Brothers
The 10-episode series produced by Steven Spielberg and Tom Hanks is based on a true story following the Easy Company, an army unit during World War II. Just the fact that it is based on true events, and has a ranking of plus 9.3 in almost all website reviews, makes it a more compelling series than fictional, out-of-this-world TV production. IMDB ranks the war story as the top-rated TV show of all time with a 9.5 rank. Not bad at all for a 2001 production.
