Alright lets get a bit longwinded there.
First off, Tourists. You know, German Tourists. The German Tourist is basicly like a Animal you take out of its usual living space. Its confused, frightened and makes as much Noise as it can to scare off any potential Predator. Okay seriously, German Tourists behave badly most of the time i assume due to "Well we dont live here". Same can be said for alot of other Tourists.
Then we got the World Wars. I'd like to point out that Germany, contrary to popular Belief, did not start World War 1. Some Arch-Duke of Austria-Hungary got shot by some Serbian dude or something and shit hit the Fan quite literally. Germany was a Ally of Austria-Hungary so thats why they fought.
Second World War is a bit tougher there. For one, the "Führer" or Leader at the Time was actually Austrian, yet they never get any hate at all for Adolf being austrian, go figure that one out. Its told in History Class quite extensively, even in Classes which have nothing to do with History directly. And while this View is probably very controversial, that single time period of 6 Years has produced massive advances in Technology, Aeronautics and Medicine for example, in part sadly due to very horrible Methods.
Wonder if we were as far as we are in Medicine today without those Murderers and Warcriminals. Or went to the Moon as quickly as we did by adapting Rockets meant for destruction. The V2? Yeah thats the first Rocket. Messerschmidt ME262? First Plane using a Jet Turbine.
So thats two of the negative Points out of the Way first. Lets get to the good bits.
Great food, of quite a variety. Germans are literally assimilating other Culture's Food

Great Music, from Classical over Metal to Techno and Industrial (AKA Goth Music)
Two big Events centered around Music, Wacken and the WGT (Wave Gothic Treffen)
Octoberfest, although thats mainly just cause you can drink, also great Beer.
Good Infrastructure, working Economy (we lost two World Wars and our Economy is better than America's, gotta think about that one)
Lots of famous People, alas sadly also some infamous ones.
People are generally nice, alas you got Idiots everywhere anyway
Could go on. Honestly its probably not the best Country in the world, but its far from being one of the worst. The History is mixed certainly and there are alot of bigger negative Events but really, which Country hasnt done similar Crap to some degree? America for pretending to be the moral Compass of the World has alot of negative Stuff under their Belt. Internment of japanese Citizens during WW2 for example, or the rather infamous dropping of two nuclear Bombs on Japan. How they stole and killed a good Amount of native Americans during the initial Settling of the land and so forth. Same goes for any Country.
They all got their History, not all of which is pretty. We learn from it and move on, trying not to repeat it. But i dont hold the History of a Country against its People, or hate that Country for some very stupid Mistake they made years ago.
That being said, im also German so go bugger :O
