Yeah, it's pretty non-stop, all 25 episodes of it. :/ Attack on Titan (or Shingeki no Kyojin if you prefer) comes out of the box swinging taking no prisoners. It's unlike anything I've seen in a long time. AoT is as different from the current lineup of cookie cutter fluff anime as Star Blazers (aka Uchuu Senkan Yamato), the anime that introduced me to anime btw, was back in its day. Star Blazers showed me that people could actually die in an animated series. I'd never seen anything even close to that before and it was a bit of a shock to my young eyes. I'd seen Wile E. Coyote get blown up many times but he never died. SB comes along and turns my world upside down. Now, many years later, AoT comes along and turns my whole perspective on anime on its ear. That's a pretty impressive feat for this old fangirl! :)

I don't know how far you are in the series but if you're struggling with AoT now, you may wanna cut and run. :/ Like I said, all 25 episodes are pretty much non-stop. I admit I was tempted to do just that myself a time or two but I held on till the end. It's hard to see it sometimes but underneath all the depressing grief and gore is a really good storyline.
