It's fine. It's fine
There were some other movies like this during the pandemic, and some of them were even quite fun. Unfriended, I remember, and the slightly less engaging Unfriended 2 - Dark Web Boogaloo, and there were some others.
This follows the same formula - you get to see the screens of the actors as they either react or blind-react to things that happen on the other feeds, and one or two are streaming from their phones while out doing the scary stuff.
The premise is basic, the plot is decent but not exciting, and it is a wholly serviceable but unremarkable piece of film.
