Yes, that's right. There's going to be a love action AOT movie coming november 22 2015 (I believe) and I'm super excited for it.
Attack on Titan is about Eren Jeager, whom saw his mother being eaten by the titans. Eren vows he will destroy them all, and thinks to his new power (turning himself into a titan) he might just be able to do it.
There's little to nothing known about the titans other than the fact that they don't eat to survive, they just eat. Also the only way to kill them is to slice of the back of the neck. Titans also have a regeneration ability that far exceeds that of wolverine's.
As anime goes Attack on Titan is definitely a 10/10
