They're trying to capture lightning in a bottle twice with much of what's been announced for Phase 4. They will not make the kind of money or impact that "the originals" made. BP2, Thor 4, and Dr Strange 2 will probably bring in quite a haul but the rest... they're going to have to be *really* good if they want to keep that gravy train a-rollin'.
And, of course, they are doing those movies/characters for the implicit reason that they can use them in all their theme parks, not just (lamely?) in California and overseas.
Back on topic now.
