Rating: 9/10 stars.
Bonus: there were two post-credits scenes! (one is before the main credits, after the stars' names are posted; the other is after the main credits)
* nice segue with Captain America - him and the punching bag we saw at the end of his movie.
* "You didn't know what you were doing." "I think I did."
* I like Dr. Banner's secret to maintaining his composure...though it raises questions if you start thinking in terms of ship.
* "Romanov?" "I'm all right. *looks at Banner in pain* Are we all right?" :)
* "Are you ever not going to fall for that?" has to be one of the best lines of the film.
* Pepper Potts is in this...as is someone I can't help but feel is Peggy Carter's granddaughter. (either Black Widow or Maria Hill)
* kinda feel sorry for Steve, though..."What's it look like in there?" "It seems to run on some form of electricity." "Well, you're not wrong."
(massive future shock for him - compounded by the stuff SHIELD has)
* "Are you an alien? A space alien?" "No."
* poor Hulk...finally found a thing he can't lift.
* "We have no problem with your people." "An ant has no problem with a boot." -Fury, Loki.
('no problem'? really?,...because you cited The Destroyer's attack as the reason for your development of weapons)
* "It alerts the other Realms that the Earth is ready for a higher form of war." -Thor.
(yay, dwarves!)
* I was really looking forward to Captain America and Stark talking about the Stark they both knew - the one who designed his shield and wasn't always there for the other one)
* "This' just like Budapest all over again." "You and I remember Budapest very differently."
* so, were those flying things supposed to be Midgard Serpent? Nighogg? (we saw Nidhogg at the start of Captain America - Red Skull pressed the eye of woodcarving!Nidhogg to obtain the Tesseract)
* the solution to the problem reminded me of something the late Dr. Asimov once said about advanced societies - they'll all be interconnected.
* oh look who's back...and running that empire. wonder if Loki knew.
and the post-credits scene:
Captain looks like he's about to fall asleep, Banner's trying not to laugh, and I'm not sure how familiar Romanov is with shwarmas. :)
