I've just seen the horror movie Pontypool
extremely and incredibly good.
If you want to enjoy the movie even more than I did, don't read anything about it at all beforehand.
It's extremely tense and yes, it IS horror, although it starts somewhat slow.
But this doesn't make it worse, this is part of what makes it so great.
It's an unusual horror movie, and not for the likes who watch it for the gore.
