Not everyone here likes Hetalia, so you probably would've been better off posting this on the hetalia - axis powers spot.
But anyway...Yes, each person is the representation of a country, and the show basically shows events in history in funnier ways. I like it because I actually loved history before it, so it's just one of those things I would watch. It's also entertaining. And made school mais fun for me. Of course you can have your opinion, but that's just mine.
