Let me be clear and say that I do not think the event is at all perfect. That disclaimer out of the way...
...there’s seven other houses. And back in the day there would still be one lighter house. So same number of straight houses this year as, say, 18 and 21.
Still, I definitely prefer the originals this year over the IPs (sans Killer Klownz). I present Nightingales Blood Pit to argue that they still do complex stories.
Also, IU has as active a discussion each year as Vault did, IIRC.
