Just make them watch the Toonami promo.
Solid review by Metal Mike there.
Um camera broke huh? 12 minutes feels long with out video oddly.
1st warning any one who is interested in the show be very careful when searching Attack on Titan merchandise..
what is seen can not be unseen you are warned!
This is a series I will be buying on disc. It is one that can bring new people to anime if its fits their tastes. The look of the characters did not bother me tho. Also closest thing to Attack on Titan out now is http://www.animevice.com/anime-vice-discussion-threads/22-2380/knights-of-sidonia-discussion/97-345411/#1 So when Metal Mike runs out of Cowboy Bebop take a peek at this.
It's not the best anime, just the most popular and overhyped series. I would not recommend Attack on Titan to a new anime fan. I start them off with something easy to get in like Dragon Ball Z, Yu Yu Hakusho, Sailor Moon, or Fruit Basket. If they are adults, I hit them with Akira, Psycho Pass or any of Gen Urobuchi's works.
To get someone into Attack on Titan, just let try the first episode if they like it or not.
