I don't know about any filler, since I haven't read the manga to know what is filler, but I binged the series with my girlfriend this past weekend and I can say that it's decent. For the most part, I enjoyed a lot of what I saw, but (And I hate to be that guy) I couldn't stop comparing Asta and Yuno to Naruto and Sasuke. Or really the basic premise of this series to Naruto.
I mean geez, I haven't personally watched Fairy Tail, but my girlfriend, who is a huge fan of the series, says that this one comes off as a combination of the latter and Naruto. Even then, I still enjoyed it for the most part and I plan to continue it, though i'll probably hop over to the manga, which is what I originally planned to do for the series until the anime started.
I'm hoping that they'll continue delving into unique forms of magic for different characters too.

I can't force you to believe me that's your choice. People live their lives bound by what they accept as correct and true. That's how they define "reality". But what does it mean to be "correct" and "true?" Merely vague concepts...their reality may all be a mirage. Can we consider them to simply be living in their own world, shaped by their beliefs?-Itachi Uchiha
