One day I will learn that the chances of coming across a decent 'found footage' horror film are pretty much zero. Apartment 143 nevertheless managed to suck me in like a quagmire of poorly written, over the top crap.
The funny thing is, since the hugely successful Paranormal Activity hit the scene, and the found footage style of films spilled like stagnant water all over the horror genre, almost nothing has managed to come close to the quality of PA.
If you like found footage films, and are the type to buy any entry into the genre, chances are you will enjoy this. It is no worse than many of the other turds that have been release in recent years, but it is certainly no better. There are enough 'shock' scenes to keep most fans of the genre happy, but if you are hoping for something a little different, then look elsewhere.
