What would have made this movie more interesting - MORE EFFING PLOT

Rating: 2/10 (31 December 2018)

The first spoiler is that the mystery of what's going on is NEVER revealed. You don't even get a peak inside the kimono. If this sort of story telling appeals to you, you may enjoy this. (we didn't)
There are so many cracks in this (not ever) 'scary' movie that I'm sure most people are filling them with some very imaginative Spackle.
The (apparent) rules of this movie;

Something in the sky (that casts a shadow) makes you go suicidal crazy when you see it.

You can be affected via a video feed (huh, ok - not really sure how that works, but ok)

It doesn't make people already 'crazy', suicidal. It just turns them calm

evangelists wanting you to join them by looking at the beautiful truth.

It requires eyesight to effect you, simply being blindfolded keeps you from going mad.

-----------
Unanswered questions;

Does crazy sky monster work at night? (Sort of the opposite of the movie Pitch Black?). It seems to require sunlight sky to 'get you'. Simply covering windows or your eyes is all it takes to not be affected. Does it work on a cloudy day? The movie never really address this obvious hole in the mystery.

What if you just never look UP into the sky? (where is seems to be) A good baseball cap could make for a great defense tool.

Why do the birds not react to ALL people affected (like the Evangelists)? Whatever triggers them to react is inconsistent (and painfully convenient to the script.) The birds in "Bird Box" (canaries in a coal mine) are just a writing conceit so they could come up with a clever mysterious title for the film.

----------
Extra rules (that I imagined) that would have made this WAY more interesting and they could have easily added to improve the story (and still not given away the mystery);

Pregnant women are unaffected. (it seemed like they were going there with the story but never followed through)

Pre-pubescent children (or younger than 6 years old) are unaffected - as soon as they reach puberty they become susceptible to the crazy sky monster.

It can't affect you in extreme darkness so travel at night is the key to moving about in this new world.

With the 'extra rules' - it would have evolved to a world where the pregnant women and children run things and sighted men are relegated to the darkness or blindfolded in the day, lead by the unaffected and making sure women stayed pregnant. (not so bad when you think about it)
About the movie - it was beautifully shot, had a number of respectable actors in it and was easy to leave on because you kept hoping something would make sense - but in the end it never does and you spend your time writing reviews that won't make any difference. Happy New Year!!
