Like a rug tying the room together

The Marvel Cinematic Universe is all about connecting one movie to another. And sometimes it is done in the best ways possible "“ by small details or minor characters "“ as said about Coulson, who ultimately met his demise (or not). The Easter-Eggs are more than just small details, blink and you'll miss it scenes or items for the hardcore fans to search.
Another fine example is Senator Stern, who first appeared in Iron Man 2, only to be revealed as a HYDRA agents in Captain America: The Winter Soldier.
What didn't work out from this point of view? Well, what about the vision Thor had in Age of Ultron, vision which was so forced that it didn't actually make it out of the editing room. Another connection which wasn't explained (in the MCU at least) was Odin using dark magic in order to send Thor on Earth before the Chitauri invasion "“ Odin, all powerful, would have deserved an explanation of some sorts for this awesome feat of bypassing the Bifrost.
And this leads us to some other issue, which we believe will be spotted all throughout any kind of shared universe. If Thor faces an army of Dark Elves bent on destroying the Universe, how come nobody else notices it? London came out pretty battered "“ so maybe at least Iron Man (who brought world peace, as he said) should have been there to lend a hand.
If connections are made, they shouldn't feel too forced "“ Age of Ultron is the perfect example for forced connections, since it announces both Ragnarok and Infinity War via the same vision.
Which leads us to another point, concerning the breaking of Joss Whedon "“ check it out on the next page!
