This season of AoS is among the best produced material in the MCU hands down.
Had S1 been on this level we might have actually had our #itsallconnected... but had S1 been on this level, we ultimately wouldn't care if it did, because it's already so good on it's own.
But on another note, some heavy speculation may have gotten some ground due to some recent spoilers going around that may be connected.
Long story short, Marvel really may have either gotten or worked out a deal for the Fantastic Four rights from Fox in exchange for X-Men TV rights. There are spoilers floating around for a certain new MCU movie that may give traction to that old rumor w/o actually outright confirming it.
Since no one is clear on the terms of the Marvel/Fox rights including the people that that work at Marvel.... there's no telling if the 2 things are connected.
But the spoilers also confirm some other speculation that's been floating around for years.
Sorry to be vague, but I'm really not trying to spoil anything for anyone, but I can share more detail if anyone cares to know.
p.s. Guardians of the Galaxy has 5 post credit scenes.
don't forget to stick around for all of them. Movie releases in the US this Thursday night.
