I saw the first one, as was quite impressed by it. I liked the storyline becuase I thought it was pretty original and well makes you think "wow, what would you do in that situation'. I really enjoyed it. I thought it was a bit random at times like when that teacher dies but he then just gets up out of nowhere and sits on the chair and rings someone(or something like that, its been a while.)
I never got to see BR2 bur from what I heard it's not meant to be as good ):
