Must say, am not a huge fan of this movie after watching, as I feel it did have some issues. Although this is to be expected of course given the natural limitations of a low budget horror.
Despite it's flaws this movie does get a lot of things rights and is a very bold attempt to try and do something different and for that alone I highly commend it as this was so refreshing to see. Was relieved not to have sat through another empty rehash.
It must've took real f****** balls to make something like this in a market that's over- stuffed and over-filled to the brim with generic middle of the road SAFE horror pics.
Some genuine creepy moments in this too. Like on a whole another level of CREEPY!!!!
As for it's flaws, it would have been great to have seen more of Alice's backstory so that we can understand more about her relationship with her father, although I understand why a lot of this was left ambitious and open to speculation.
Also, some of the best bits of this movie are when the two girls are uncovering the fate of those who were trapped in the apartment before they were (won't spoil it here) but it would've been great to have explored this more and to have seen more evidence of 'those who came before'
Certainly don't regret watching and would recommend.
