If the Twisters rumor is true, I can understand it as a first step, especially because it can fix something that a majority of people have been clamoring for since Supercharged opening, a replacement...
It's a recognizable property with enough appeal to freshen up the area, but it's also not one of Universal's "crown jewel" IPs that you'd want to build an entire land around.
I'd much rather see Universal save properties like Back to the Future, Jaws, and other legacy franchises for projects that can actually do them justice, rather than forcing them into an existing building as a quick fix.
And who knows? Maybe Twisters ends up being a better fit than people expect. If it succeeds, great. If it doesn't, Universal hasn't burned one of its biggest franchises on what was ultimately intended to be a transitional project.
I get why people want Universal to go all in, but I also think it's easier to say that as fans than it is from their perspective.
I've mentioned this before, but Universal already
did spend a lotta money at USF over the last 15 years; so the problem wasn't a lack of investment, it was that many of those investments didn't age well (or in FF's case, hit at all.) At this point, though, that's water under the bridge. We're already here. There's no undoing the decisions that got USF to this point.
But from their perspective, I can understand why it's hard to justify saying, "Well, that didn't work... let's immediately spend another billion dollars," especially in these current times.
Fix Supercharged. Add a dark ride to DreamWorks Land. Tighten up Minion Land to Minion Studios. Replace Simpsons. If they all hit, USF will be just fine.
