So I saw this in theatres. I also managed to find DVD copy ( I think the dvd was released in the UK already?). It's an amazing movie, i've seen it 3 times so far and I've been telling my friends about it, everyone loves it.
If I were to have a complaint it seems like the movie was kinda slow at the beginning, the first death isn't until 45 minutes in. The end really picks up for it though
