Saw the movie yesterday. Second best Marvel movie. Right, like so close it can feel it's breath on the back of it's neck, behind Avengers. Just great all around fun from a cast of characters that there isn't too much backstory that people know. So they can fudge a few things. But god damn it was a fun ride.
And yeah, the Orb was Power. So far we've had Space(Tesserect), Mind(Loki's Staff), Reality(Aether), and now Power(Orb). All we're missing is Time and Soul and then Avengers 3 hits and it all comes together. ALSO! In a blink and you'll miss it moment we did kinda get a hint at Soul.
In the Collector's Collection is Adam Warlock in his caccoon so we could be getting Soul very soon.
I can't wait to see what they do next.
