i saw the lower level was blocked but an immediate reaction was "go upstairs and get out that way!" it wasnt really handled imho and it reminded me of Resident Evil game where you simply cannot leave the place because there's a dog in the way LOL - Rec was a good film well made, kept your attention but nothing original - it didnt persist with the documentary aspect too - only 2 horrors of the found footage/faux documentary have pulled it off quite well The Poughkeepsie Tapes and The Tunnel
