In all, not very engaging as a story. The idea of journey as blindfolded with two small blindfolded children is not compelling or thriller; it's anxiety-producing. Especially since the protagonist (Bullock) is basically unlikable in this role. The whole premise is preposterous: traveling in a boat blindfolded, driving a car blind, etc. Also, there's an element of child abuse with "boy" and "girl" who've spent their little lives with the Bullock character as non-entities, until the ending in which there is supposed to be some sort of validation of their presence. I realize this is based on the book, which came out before A Quiet Place, but the similarities are undeniable, and one can't help but compare the two films. There were inadequacies in A Quiet Place as well, but it was a much more compelling film than Bird Box.
