We liked it a lot. My son shouted (loud whisper) HULKBUSTER ARMOR! Then later got all excited when they were building Vision and whispered "it's Vision! Daddy it's Vision!" When he actually emerged, a woman behind us goes "Now who's that?" And the guy right behind us says "I don't know. Some dude named Vision. Ask that kid."
The only stilted part was with Hawkeye, and even that was more effective than it could have been.
As soon as the Iron Man/Hulk fight started my 7yo and me started whispering "Hulkbuster! Hulkbuster!" and nudging each other.
The only part that even remotely compared to his excitement was when the Helicarrier appeared.
No question we loved this movie. If you go to the movies to watch stuff blow up it was great.
ALSO SPOILERS:
The hulk armor was cool as hell, I don't really know much about the comics son had never even heard of it before.
Same thing with The Vision, I had no idea he was even a character in the universe so I actually thought Cap was gonna freak it up for Tony and kick off what ultimately leads to Civil War.
I'm itching to find out what the firestarter is for Civil War. I'm assuming it'll be quite different from the comic series. And will it end the same as the comics?
