The story was very good. It was exciting and attention grabbing. The concept was amazing. Being able to control ancient beasts using modern technology. In the first season, the art was very...rough and not good. The characters were ugly, to be frank.But as the second season and third season arrived, the art improved and the charcters became more good looking and clear. The sounds were very good. They were catchy and upbeat. There were mostly of rock genre. The character profiles were okay...Some characters were not clear and due to that were ignored. This is the show to watch if you're bored. Basically for those who have never seenanime before. After watching this, you would want to watch more and different anime. It piques your interest.
