There were a couple of dialogue issues in the movie where a line didn't come out right. However:

There were multiple "no way" moments where I feel glad I was alone on my row because my nerdiness was very audible.

There were multiple breeches of the fourth wall that were perfect. Just so good.

Overall the most fun I've had at a Marvel movie in a long time.

Oh yeah and it is 100% R rated. About a zillion F bombs, lots of inappropriate dialogue, insane gore.

Definitely won't take the kids to that one.
