I really liked this movie, and it was refreshing to see a movie diversify the narrative and bring something new to the table of films of its genre. As others have mentioned, it's super thought provoking, the cast is amazing and the chemistry is great; it's heartbreaking just as much as it is heartwarming. I have almost zero complaints... *almost*.
I wasn't gonna say anything, but it's been a few days since I've seen the movie and it's still bothering me so here it is: I really didn't appreciate that one incredibly biphobic line where Erin explains that she's afraid to commit because she's been burned before by a girlfriend who 'went back to men'. The whole scene leading up to that was great; it had me on the edge of my seat and I was bracing myself for the heartbreaking story...but to then have the ex-girlfriend's big, oh-so-terrible betrayal be to simply be bisexual and exist?? That just really... let me down. It made me feel really gross and alienated as a bi person, and even just objectively speaking it felt so out of character that it jarred me out of the otherwise pretty inclusive and accepting narrative of the story.
I thought maybe it could have been just me misinterpreting or being overly sensitive, but as I looked to the other non-monosexual people in the room and saw my own reaction reflected there, I knew they received that line in a very similar way.
Even if the intent behind the writing in the scene wasn't to invalidate the experiences of bi people, that's exactly the impact that was made in my opinion. I wouldn't condemn the whole movie for it, it was really cute and heartfelt and relatable, and I enjoyed it a lot otherwise. But, I wanted to take the time and write this out since nobody else seems to be saying it.
