It was the hardest the event has ever leaned into fan service (yes, I also attended 25). The whole "everything is connected" gimmick -- which felt like a stretch even then, evil schoolgirls and bikers and the guys you ripped off from Buffy all live in the same universe? -- gave online fans a sense of power, like knowing the houses before all your friends do or learning from the Behind the Screams tour that the masoleum names are all the actors from The Brady Bunch.. And they kept it up through the event, culminating in a dozen or two super-fans actually getting to take a part in the final show. Even though relatively few got to do that, the fact that they did was mind-blowing to the online community.
Also, her show was solid. The set was large, the effects were surprisingly gruesome. Eelmouth, the main MC, did a fair amount of ad-libbing and was played by actors who would also be fan favorites as Jack the Clown and Otis T. Wren, so they knew how to work the mic. Backed up with an overall solid house line-up (two GOAT in there for me), and the last event in IoA. In other words, a solid event only improved though the lens of nostalgia.
