Attack on Titan

From Asaction

Hugely popular and often gruesome tale of derpy naked giants who eat people for fun. Mankind has sheltered itself behind huge walls until one day the Colossal and Armored titans go all Ronald Reagan on it and start kicking holes in the wall. (Is anybody going to get that reference?) Eren the angsty kid and his friends Mikasa the badass and Armin the nerd join the army so they can pwn titans, even though most of the soldiers in the army pee their pants when actual titans show up. There's lots of angst and tweests and internal monologuing and severed body parts and the first opening is about the most over-the-top epic song you've ever heard.
