I don't know what all the hate is about, but I rather enjoy this show! Ya the MC is OP from the very beginning, but hey I like anime like that lol. Sometimes you just want to watch a MC trample everything and everyone in their path and this show doesn't let you down this that! Give it a try. It reminds me, so far, of "In Another World With My Smartphone". Both MC's have unbelievable magical aptitude. I would be okay without the odd incorporation of romance, but overall it doesn't both me! Regardless, give it a couple of episodes and understand that the MCis just waaay OP and you'll gave a great time.

Hope this helps!
