Code Geass, Elfen Lied, Death Note, FMA Brotherhood to name a few. Code Geass especially. That one had a LOT of crazy twists.
If you want alot of crazy plot twists and enexpected events that blow your mind defently check out Death note and Code Geass Full meteal Alchmis and Full mettal Alchmist brotherhood also has alot of unexpected events. Although I do no like bleach and would not recomoned it there are some unexpected events some of which were very shocking.
If so...samauri Its like, on Toy Story, Woody(cowboy) vs Buzz(space ranger) Ninja and space ranger are both better than cowboy!
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
