For all of its shortcomings, I will still give them props for attempting to dabble into the action genre again with Kyoukai no Kanata. I hope they've been able to take some good learning points from the series and will be able to apply in their future works.
I'm still disappointed the show never lived up to the first 20 seconds of the trailer below, hell they didn't even use the PV song either, not even once lol
