There is one thing I don't like about Disney taking FOX, and that's the impact it's going to have on Blu-ray prices. (Probably a short-lived problem with the way things are going, but for a physical-media-wanting person such a myself, it doesn't look good.)
See it used to be that most Blu-rays would be 15-17 bucks at launch, and then jump up to 20 and stay there until the market dragged them down to the bargain bin. Not so with Disney. When Disney would release one of their major animated movies, it would launch at $22, and then go up to $25, where it would stay for all eternity, unless it was more of a Pocahontas or Oliver and Company kind of release (The movies nobody but the collectors really want). Disney could do that because they were Disney, and people really want to own their stuff.
When Disney bought Star Wars, the same thing happened to those movies. You're still going to pay about $20 if you want Episode VII on Blu-ray.
The same thing is happening with the Marvel movies, although they've been more inclined to drop in price after a few months than the Disney and Star Wars releases were, but they still cost more than they would have back in the day.
Anyway, long story short, I really don't like what this is going to do to the Blu-ray market.
