I loved that scene as well. It really gets across just how differently people can feel about cinema, the guy is just a normal bloke who is into mainstream films yet for Chan cinema is almost a scared art form. It's something that happened to me before, where certain films I see are filled with all these gems or moments of truth about our world yet if I show the film to someone else they end up saying cool it's about a a guy getting redemption and it has some cool long takes. Also maybe I'm looking too much into but it made perfect sense that her intense dislike of Nolan is matched by her love of Wong Kar Wai(Imo Wong is the cinematic opposite of Nolan)
My favourite part along with her coming to terms with the fact she has to save herself and maybe art isn't worth committing you're whole life too, was when she comes to the realisation along with the help of an imagined Leslie Cheung that she hasn't been rejected by someone she loved, it was more that she was just lonely.
It felt like a like romantic comedy fit for the 21st century.
