9/10 When it comes to horror.
As a horror fantast, i know that any horror above 5.0 on imdb is worth while watching. A 5 is a 7 etc. This one is a really good one. Well done special effects and the creepy clastrophobic feeling is grasping you really tight. With the first person view it's almost as if you're down there UEing yourself. The best part is however the plot. It gives you adventure mixed with horror. And everyone knows that adventure with anything is a solid foundation for a starmovie!
I give this one a strong 9. I would give it a 10 if it were not that i felt some connections to the cave while watching it. That was only due to the atmosphere though. The originality of it is gold.
I watched with some mates and even my best friend's girlfriend liked it. This means it is enjoyable even by non-horror fantasts. So bring the club and enjoy - imo - the best horror movie of the year!
Because im god, are you god to question my answer?
