"Bird Box" is a worse version of "A Quiet Place" only here people don't have to see. Sandra Bullock and others do a good job but their characters are flat and you can't get attached to them. Plus these I don't know whose idea it was with all the flashbacks throughout the film, but for me, at least, they cut the thread of the story. Although I've seen the concept before, that doesn't necessarily make it bad, but the fact that there is no explanation of what it happens and where do these creatures come from, we were a bit left in the air throughout the film. We were waiting for an explanation at the end, but nothing happened, although the ending was not bad.
