Hetalia Axis Powers is basically... Well, it's set sort of in the WW2 era but there are some references to other time periods... The characters are all named after the countries they represent, but they have human names, too... Um...
It's basically a comedy series. Each episode is about 5 minutes long. It originally started off as a webcomic series by Himaruya Hidekaz, but soon became very popular and even has a movie now. Though I haven't been able to find it anywhere... Hence my 'can't-find-a-movie' complaint...
This is the main wikia page for it, since I'm not very good at explaining things... ;.;

Oh, pre-warning: After the first episode, you may either think it's stupid or become hooked on the series. After the second or third episode, there is probably a 95% chance or more that you will become hooked on it. XD
Dad didn't believe me when I told him. ...Until he watched the first 2 episodes. ^^
