So they give an IP that not a lot of people have heard of an attraction (Bourne) and there's currently rides based on old comics in the parks (who's heard of Dudley? Cause I haven't), but they won't build an attraction based on one of the biggest TV shows to come out in recent memory? One that allows for plenty of call backs to old attractions and movies (BTTF, Jurassic Park, etc)?
That makes no sense to me. I love Universal, but they criminally underuse a lot of IP's that they have at their disposal (Marvel, Fast and Furious, Universal Classics, even Jurassic Park to an extent).
That's an extremely narrow way to look at things. I love Stranger Things, but Universal is already doing the most of what they can with the IP using it as a haunt. Not all IP's are equal. Some are slam dunks, like Potter. Some lend itself creatively to an attraction, like Dudley, or more popularly, Splash Mt.
