Who wrote this dumbass trash

Rating: 4/10 (10 July 2018)

I'm about 30mins in and have decided it's a dumbass movie, why? After sending in various teams into the shimmer, including army personnel, they now decide to send in a female unit, various fields of relevant research but, they are carrying guns? Why? There have been no military attacks, no firearms detected, basically no-one has come out alive except for one military person, without a gun.
So, here they are going into the shimmer with guns but no breathing apparatus?
You'd think that would make more sense, yes?
Hence the dumbass title.
I don't care how good the story is after this, the decision to brandish weapons and no breathing apparatus completely undoes that.
I am curious so I will try and watch further and maybe it might wow me visually, the guns kind of spoil it for me at this point.
