I'd rather they stay separate.
Disney could seek control of the MCU and propose a buy-out for that specifically, but FOX needs to remain as is.
Under the Disney umbrella, will FOX have produced Hidden Figures, War of the Planet of the Apes, Alien, Murder on the Orient Express and Kingsman? I don't think so, unless the strategy is to have those types of films produced for their OTT platform.
Still, not a fan as this will push more consolidation in the content business just to catch-up to the likes of these bigger companies.
