It's shit. Skip this one
As a big horror movie buff, I rate this movie barely 5/10. It was just crap, acting was ok for this kind of movie, but the plot was non-existant. The only good thing was the ending and them waking up in another dimmension or something. Other than that, this is a shit movie and how NOT to make a horror/cosmic terror movie.
I liked The Thing, Beyond The Black Rainbow and similar movies, but they all had style too, and you did not need to watch other movies to understand them more.
The Void is just a ripoff. A joke, seriously, apart from FX it has nothing to show.
