This format has been done to death and there is nothing new or original in this one, they took none of the opportunities that were available to explore the concept further.

Most recently, John Krasinski's - A quiet Place explored the story arc of "you have to be silent or the monster will get you" and now here we have "you have to be blindfolded or the monster will get you".

The character development is awful, they had John "Malcatraz" Malkovich in a leading role and utterly failed to use him for anything meaningful. The other characters came and went, none of them standing out in anyway.

Even the ending is a straight up clone of Day of the Triffids. The huge number of stolen and unoriginal plots devices would have been cool if they were paying homage and putting in references for fun but they were not, this is just lazy, B grade film making done to generate a bit of money, nothing more.

It's a watch once and delete movie. This one will not be remembered and the fact that it has been nominated for awards genuinely just confirms that the current day awards programmes are corrupt and worthless to the end viewer.

There are dozens of other horror / sci fi movies with the same plot and most fo them are better than this. Watch one of them instead and dont waste an evening on this.
