Even though I was spoiled on the 9/11 joke, I still laughed my head off at it.
What I liked about the movie was how fleshed out the characters where. That was shitty Kumail to not tell Emily about his family and not wanting to meet hers, but I did see where he was coming from. Even when Kumal's family shun him, they don't stop loving him. Its easy to believe that they will make amends in the future.
I was surprised how much I liked Romano in this. The only thing I knew him from was Everybody Loves Raymond and that never interested me. He was good a the well meaning guy who doesn't quite have a way with words.
Hunter's best moment was when she flipped out on the racist heckler. "Why would you want ISIS to have more fighters?"
I was thinking a more believable ending would be Kumail and Emily not getting back together. I couldn't blame her for not wanting to get back with him since he did say to her that he didn't know if they had a future. It would be a touch of realism if things didn't work out. That said I had a big fucking smile when she showed at the end. Her seeing Kumail's onstage break down is a believable reason for her to give him a second chance. Finally the real Kumail and Emily are married, so I guess it was a realistic ending.
