Maybe I missed something? I watched the entire movie and more than anything it didn't make much sense. I'm pretty disappointed at the lack of luster.
I can get behind a move with little to know dialogue (a quiet place 1 and 2), this one has two lines that repeat at different times.
In my opinion it's missing a little back story, the character has little to no common sense when it comes to self preservation. The director make her dimwitted at times of crisis.
The CG was good, the end didn't really fit to me. Without giving anything away I just thought it could have been done much better. I see this as a great opportunity to make a very good film that they rubbed poo all over.
Suspenseful but not scary.
