I probably saw this movie 7-10 years ago.
I remember 3 scenes from the movie..
1. Group of people from a town watching a very large tree in the forest being cut down.
2. New girl at a highschool is being shown around the school and she is amazed by a water fountain “unlimited water whenever you want?!”
3. New girl attacks a student by controlling Vines and tree roots.
As you can probably assume, the movie is about a tree that is cut down and the tree awakens to be a teen girl that attempts to take revenge for her death…as a tree… Or something like that.
