Good watch, might watch again, and can recommend if you're considering it.
The "feel" of the movie reminds me a lot of "Booksmart", but almost more "versus" than "cooperative", if that makes sense to you.
I'm a big fan of Hannah Marks, and less so of Liana Liberato, and while the focus is typically on April, it really felt like they should have been cast in each others's roles, and it's not like Liberato can't carry a lead role. The roles just didn't feel intuitive, and the movie does one of those things where I feel like it's trying to tell me who's hotter, and (for me) Hannah Marks makes more sense as the "hot new thing", and she's the stronger personality. But that's probably why she has the lead here.
It was also frustrating ...
