Pros: Not overblown. Beautiful cinematography. Well acted.
Cons: I'm unaware if there was a time constraint, but more time would've allowed more suspension to be built.
I should be honest, my speakers have gone and I had no access to headphones - so I can't judge the sound! However, based on the video - I can only imagine the sound enhances it. It's creepy without being overblown (which is a common bugbear of mine). Can't wait to watch it when I find some headphones!
