Eh...
Honestly, didn't find this all that good. Had a couple little chuckles with some of the Night's Watch bits, but this honestly felt pretty flat to me. For me, the quick cutting of it all made it feel like a bunch of punchlines with no real set up to them. On top of that, being random doesn't equal out to being funny either. I mean, probably my favourite bit of this was the "Class of 89" Night's Watch thing, which I thought was pretty decent, up until it got to the "Now let's go talk to the random magical tree" part of it. It really just didn't work for me, which I guess could be said for the thing as a whole as well.
I'll probably check the season one episode out, and if I'm still not enjoying it stop around then. Hopefully this'll be something that I do wind up enjoying but it probably will just be one of those things that doesn't match my taste.
Regardless, best of luck to the series, and at the very least, it's still miles ahead of Mahalo's introduction and production!
