Haven't seen Quarantine, but I have seen the original, [REC], which is a Spanish movie made one year before Quarantine was made. And based on the previews for Quarantine I saw, it seems to be a shot-for-shot English remake of [REC].

I will say that [REC] is pretty fantastic, and it actually scared the living hell out of me, especially the ending. I highly recommend it. Quarantine I'm not so sure about.

Sunshine is amazing, though, definitely keep that one on your list.
