Absolutely. Universal can and is competing directly with Disney now. To do this effectively, they absolutely need to build family-friendly dark rides. EU should have included a Fantasyland-style area with three or so such rides, even if it violated the one-IP-per-area rule. Heck, ideally each park should have such an area. Ironically, Universal actually has a surfeit of appropriate properties, a veritable junk drawer full of family-friendly IPs - Dreamworks, Illumination, Aardman, Woody - and popular properties that, while Universal doesn't fully control them, are heavily associated with the resort - Spongebob, Scooby, Seuss, Bullwinkle, etc. That isn't even delving into non-animated IPs that could produce fun dark rides - a slightly spooky Beetlejuice ride could be perfect. Its actually a pretty glaring indictment of Uni that the Minions and Potter don't have an AA-heavy (even simple AAs) dark rides, that Seuss only has one such ride (with a height restriction), and that the Dragon area in EU isn't getting any. They seem to be actively avoiding them.
Also, stop coming up with alternatives for Animal Actors, darn it. Universal isn't going to come up with a more rewatchable show in that space. I know its odd, but the five things I don't want anyone touching in the resort are Spidey, ET, AA, the Make-Up Show, and the Prop Shop, and the last one is already gone. And obviously I, a random message board poster, should be the arbiter of what stays and what goes at the resort.
