Attack on Titan is a well-known anime and for good reason.
The anime boasts spectacular music, animation, and storytelling to produce a strong contender for the best anime of all time. I have been hooked since Season One and it has been quite the spectacular ride. I loved Attack on Titan right up until the Marley arc (though the introduction of arbitrary and as-of-yet unexplained memory-altering powers was a hard pill to swallow). Current Attack on Titan is what you would get if you told your hyper imaginative, incredibly undisciplined four-year-old to write a story. So many things are just forcibly jammed into the story without any sense of cohesion for it all.
Before the anime, I hadn't heard of the manga that it's based on. However, once I was caught up on the anime, I began reading the manga because I just had to see where the story goes next. From the very first episode, the story has been an emotional rollercoaster ride. The anime had me hooked from the death of Eren all the way up until the Titan encounter during the first mission. It was a complete shocker and set the tone for the anime and its story. From the first episode on, the anime put forth a doomsday tone and an atmosphere of despair. The odds were overwhelming. Mere humans hoping to take down titans anywhere from 3x-50x their size. However, humanity remained strong and attempted to persevere. In the first episode, the outermost wall is breached and the devastating rampage of the titans is brutal and sets the tone for what's to come.
