Yeah, it's one of those anime where, despite seeing all its various flaws, it was still a guilty pleasure while I was watching it. Love the action scenes.
As for the Fate series, Zero will be posted here sometime in the future. And with GO, I have no plans of falling down that rabbit hole. From everything I've heard, it's fairly addictive once you start, and I have enough time commitments as things currently stand.
