This movie is a bit of a throwback. The premise is that something creepy and eerie starts happening when a masked cult surrounds a hospital with a group of people stuck inside. This boils horror down to the basics: put some people in a creepy environment they can't escape from.
I struggled with how to review The Void. This movie had some really good elements, and some elements that didn't make a lot of sense. I think it ultimately came down to there being a lot more story than there was time to show.
The Void has the feel of an older horror movie. The monsters are not CGI, but appear to be actual props made for the movie. This gives them an unreal, yet creepy look. Think of The Thing. The special effects don't really hold up by modern standards, but it works in the environment of the movie.
There are a few odd scenes, alluding to one of the characters child and wife, who I presume are dead. There's not a lot of explanation about this, other than it seems to haunt him. This stood out to me, as there is really nothing else to tell us what's going on with this. I think this falls into the category of things that probably had more story to them, but got cut out in editing.
Once you get to the third act, this movie really picks up. Everything is set up, and we start to really get to the action. Although we see a few of the "monsters" earlier in the movie, they are all over the place through the later parts of this movie. Although a lot of it is essentially narrated, the actor playing the doctor has a great voice for this. For me, this made it a lot easier to listen to everything being explained.
Overall, I'm giving this one a C+. I was torn as to what grade to give. The earlier parts of the movie are OK, but not great, and the later parts are a lot better. Fortunately, The Void is available on Netflix, so go stream it when you want to watch an old-school style horror flick!
