Attack on Titan was a really good anime. I recommend to people who like action packed adventures. I thought that the use of grappling hooks was a good idea and swords.
SPOILER ALERT: When the titan brawled the other titan with the big nose it was really action packed and cool. It got pretty brutal though so don't watch if you're squeamish or unless you like big naked guys with no privates. I give it an 8/8 m8.
