It's a different kind of movie, and I think I liked it
When I'm not sure how I feel about a movie after I watch it, that's usually a sign to me that it was worth watching.
This movie starts out like you're along for the ride with a bunch of kids on a school field trip, then the main character goes on an odyssey without a destination and you are tagging along. Then things take a creepy turn and escalate. There's a lot of "slice of life" stuff and a pretty unexpected shift...
It's best not to know too much, and I think there will be some "love it or hate it" with this movie and its main character. She's great in portraying the kind of person who this is supposed to be. Young and free and unafraid but unsure.
