Downton Abbey! It's a series set in Britain during the time of pre world war 1. Everyone's eventually drafted and some die. It's originally about a nobleman family of high prestige and it shows a huge storyline regarding the royal family and the workers. The entire thing even has amazing imagery. Or you can try Doctor Who! It's a series that also has an amazing storyline. What I like about it is that there's very little details in every episode that contribute to the huge storyline of the series. I've even gotten interested in Lost and Breaking Bad as well.
One Fall, The Fat Boy Chronicles, Playing For Keeps, Waiting For Forever, Red Dawn, Camp, Hard Flip, Never Back Down, Overcome, White Chicks, Jump In, 16-love, Blue Crush 2, Street Dance, Abduction (which has Taylor Lautner casting in it), The Forger, Footloose, The Hunger Games and The Host, Now some of these are rated pg and some are un rated but their all very good for both boy and girl Tweens and teens
