I also just cracked up at Elliott and Ro's faces when Ruthie asks what happens if one of them says something weird that alters the dynamic of their friendship forever. And an appalled Elliott telling her older self that she's not going to FaceTime her mom while high. And the whole defensive "I let her talk to me about a hummingbird for forty-five minutes!" which just was SO (actually) very young adult daughter.
Seeing it with my own daughter was a trip in some respects. I had a few concerns about that because Elliott goes from thinking she's only into girls to falling hard as hell for a dude, but the movie made it very clear that she's still also way into girls (her older self has a girlfriend) and L thought it was pretty realistic as far as realizations that your sexuality might not be exactly what you think. (I mean, she had sort of the opposite thing where she took a while to really realize, no, she's only into women.)
I kind of feel like I'm underselling the part where it's honestly really funny when I talk about it because of how overwhelming the feels have been for me at parts of it, but truly, it's a delightfully crafted hour and a half.
