It's been open in Orlando since before the parks closed for COVID and we know it's not much to get excited about. I'll give DL props in that this was an added ride to the park, so there is something to be excited about in that and it's also a pretty decent people eater.
Overall though the ride is just sort of okay. imo, it's a type of ride that I think USF or USH could use and while modern compared to other rides at DL, it's still very family friendly and slow. DL needs something that's a bit more intense which is why I am okay with people who want TRON to come there, although TRON is kind of more style of substance (read: beautiful lights over a coaster with anything new to deliver) and it's very short which is why I still struggle with if i'd have it replace the classic rides that it'd have to. I'd like to see them create a unique coaster for DL so the park isn't getting another clone.
Simpsons had nothing to do with why he bought it. Nor did Avatar on it's own. Hulu played a big role and Fox's back catalog of films (so the collective IP, not just an Avatar or Simpsons), which Disney was going to need to enter the streaming era. It also helped diversify Disney's film catalog as it gave Disney a bunch of R-rated titles and award winning titles along with FX, which is sort of Disney's HBO, and Searchlight Pictures, which is constantly putting out award winning/nominated films every single year.
If you ask me where the problems are at Disney, I think that they should sell Hulu, and Sell ABC and/or ESPN in a package deal. Lastly, cut spending at Disney+ on original content while also adding more library content to compensate. Possibly sign a distribution deal with other streamers for certain Disney movies (non-Marvel/non-Star Wars/non-Avatar), which would bring in added money to offset any potential losses at Disney+. Also, reign in overspending at the parks. The money spent on each project seems to be ridiculous.
The Fox assets (outside of Hulu) are not an issue at all and doing what I laid out would get them out of debt and slim down the company to where they should really focus.
