I...don't appreciate games like this.
I don't appreciate games like this when they want to be reflections of what's happening in real life.
I quickly suffered darkness-induced audience apathy from it.
It isn't attempting to reflect anything from the real world other than being WWII-inspired. It's a very gripping story when you combine all three Little Tail titles, and I recommend trying it some more. There are a lot of light hearted moments the more you play through the game too.
edit: If it helps any, try out Tail Concerto or Solatorobo instead. They're much more in the cheery anime angle.
