It looks great,but the plot is nothing special. It´s worth watching.

Of course, if you refuse to watch something based on the originality of its plot, you'll skip a lot of good things. There's originality and then there's quality, and Shingeki no Bahamut has the latter. Tons of movie tier animation and a perfect execution of the story it sets out to tell. Feels more like a good adventure movie than an anime.
