I think it is still too early to pass judgement on the show, but so far i have been getting mixed feelings with wizard.
For starters, i haven´t been able to really get into Wizard, i have really liked some episodes/moments of the show, but then there were others that while not bad, weren´t all that great either.
I feel that Wizard is taking its time to establish itself, and i really don´t mind, the show does seem to be trying to stray away from the formula, i mean, i liked W, OOO and Fourze but i have to admit that those shows were a bit too formulaic, so in a way Wizard is kind of refreshing. But going back to the pacing, i feel that the show hasn´t really "started", and i am ok with that, i like it when a show takes its time to build up things, it doesn´t need to be a rollercoaster from day one, i just hope that the show does take us to some interesting places, there have been a few hints so far, but none of them have really paid off.
As for our main character, Haruto, at first i wasn´t particularly impressed with him, it seemed like fairly generic protagonist, but then we got the Flame Dragon debut and we saw some of the cracks in his armor. I really liked that scene since it´s been a while since we had a truly flawed hero like Kenzaki, Shinji or Takumi, it would be nice to have a protagonist that it´s not perfect and has issues to deal with again.
So yeah, i have liked Wizard so far but it hasn´t exaclty blowed me away yet, but i won´t lose hope that the show still has some great things waiting for us.
