Attack on Titan

I'm not an expert of anime. But I can assure you that Attack on Titan will keep you interested from the very beginning thanks to a gripping and original plot. There isn't a single boring episode, it's always suspense and action. It may seem a superficial fantasy anime but it actually deals with important topics, such as freedom. Furthermore, the soundtracks are so good that you will start feeling patriotism for an imaginary country.
