Nothing too surprising. This is Woody Allen in Manhattan.
"A rainy day in New York" came to me as a rather naive and refreshing way of doing what W Allen does. Gastby and Ashleigh question what they are and what they are becoming. They do that - to my perception - through the eyes of someone of their age. They think but do not overthink. Action immediately follows. They do not get lost in doubts and do not have to deal with an ego bigger than them. They act, they feel, they learn and repeat. They have so much to learn from that one day. I found all three young characters likeable and empowered, and the actors on top of their game (Timothee Chalamet, Elle Fanning and Selena Gomez). I would have loved to spend that day by their side The rain never bothered me anyways.
