I have a hard time getting on board with this ship because of the height difference. Even in the book, Elle is 5'3 while Noah is 6'4 or something. It almost looks like she's a child in comparison to him.
On screen you can see the difference (she's wearing heels here too):
I really like their dynamic though, and I can relate to Elle so much through her personality. It's a classic make the arrogant boy care story. I love it.They're dating in real life which makes it even cuter.
If you haven't seen it, I highly recommend it. It's on Netflix (2018)
