I went in thinking I would dislike and be annoyed, but I was so surprised! The two sisters, Kat and Vi, are both so likeable and not. I loved how sharp and determined Kate was, how unhinged and real Vi was. They were both incredibly believable. It was really fun to see the two different personalities come together. 
 The dialogue is great. So many specific, original moments that made me love Kate. 
 "It was weirdly endearing to hear the phrase "having senses" come out of Jeremy's mouth--it had been such an intrafamily reference that it was as if he'd prepared Wonder bread toast with cinnamon sugar for me while we watched Rob Lowe in Class." 
 "Vi would never pick up emergency supplies; the only way she'd acquire them was if I carried them into her house, which I made a mental note to do." 
 And the ending really shocked me. I wasn't expecting a twisty ending, but we get one. It's interesting that this person is so supposedly boring and plain, like Kate, makes such a bold, polarizing, risky decision that will totally upend her life. Something I wouldn't have thought she'd ever do.
