Maybe my feelings will change more episodes in, but after watching six episodes, I find the show very very average. The concept of warring families is kinda cool and Kazuma Yagami has a selfish attitude that's mildly interesting, but it's surrounded by problems like a generic female lead (you know, the kind that has a thing for the male lead but constantly denies it and blushes whenever teased about it), some surprisingly substandard Gonzo animation (save for the action sequences, that is), and a very 'blah' soundtrack. The dub's all right, though.
It's far from the worst, and it's not a chore to sit through or anything, but if you go in expecting something unique or "OMG that's awesome!", you're likely going to be disappointed.
