I don't think that new design is bad, it is just differentThe change of the design confused me a bit, however I am glad that DxD got a 4th season.. many good anime are unable to get the 2nd seasonI can't be sure that everyone didn't like the 3rd season, but in the russian-speaking community was very unhappy with the finale of the 3rd season of the anime. I hope the writers return to the storyline in the novel, and would not conduct further experiments on the plot as it was in the 3rd season.
