I actually hate that Disney - Fox deal.
It's too early for me to have a real opinion on it. There are things to like and dislike, it just depends on how Disney will run things if/when it passes the required regulatory approval.
For instance, I've read a lot of people being concerned about what this means for the R-rated moves that are really well done (not just Deadpool or Logan, but in the past things like the Die Hard and Alien franchises), but honestly Disney is literally buying a way to keep doing those things. All they need to do is keep the 20th Century Fox branding alive (and they should anyway--it's got value) and release anything under that name/branding that they don't want directly associated with the Disney name/branding.
Another thing is the impending arrival of a digital streaming service that Disney already announced earlier this year. Acquiring the Fox movie studios catalog can really help make that service quite good...but again, it depends on them actually utilizing both the current Disney back catalog titles as well as the *entire* Fox catalog.
Those two things I mentioned are possibilities for something good to come out of this; but if Disney just completes the purchase and stuffs Fox and all of the things they've done so well into their "vault", then yeah--it's not looking good.
