Match up parody scenes with original movies.
SPOILERS, if you can't tell that from the title of the thread.
Obviously, the overall theme of the big company guy running the girl and her small cute store out of business is from You've Got Mail. Also the whole idea that Manhattan is part of the story can be from You've Got Mail, but also When Harry Met Sally, Serendipity, and many others.
The couple telling their story over dinner throughout the entire movie may be from multiple romcoms, but the primary one that comes to mind is Forget Paris with Billy Crystal and Debra Winger.
The second meeting in the bookstore was just like When Harry Met Sally.
A review said that one of the "tasteless" scenes in this movie was from Crossing Delancey, which I've never seen. What about the whole superhero costume scene? Anything there? Made no sense, otherwise.
"I'll have what she's having" was a line from When Harry Met Sally.
The idea that the female lead almost marries the wrong guy reminds of some Jennifer Lopez movie (The Wedding Planner?) where she agrees to marry some dope her father likes. It made zero sense in that movie, so in this movie when Amy Poehler is asked why she got engaged to someone who wasn't right for her, Amy says, "it was just a mistake, let's move on."
The sister at home and the kid were straight out of Jerry Maguire. Also the woman in the conference room who agreed to quit and leave with Joel.
Two people getting fixed up who have an unfortunate first impression from an accidental prior meeting is from ????? Can't remember.
Whatcha got?
