Band of Brothers is the best of the best when it comes to portraing war movies and shows in general. I think this show is one of the best series I've watched in my life.
The show is about the ordeals of easy company during world war II. It's a story about sacrafice, friendship and the brutality and ruthlessness of war. I really like these kinds of shows were they show you the horrors of war and introduce you to characters you can have an emotional attachment to. Something you can only truely appreciate by the way when your favorite one dies.
I know this show is a few years old by now but I just watched the whole thing again and I have to say that I still like it just as much when I first saw it. This show is the a legend. They can't make anything like this ever again. (They tried with the Pacific and although that was good too, it didn't have the same impact on people like Band of Brothers)
