Never mind that the premise of a building defending itself is both corny and cliché, this particular movie manages to wreck any kind of semblance to decent film-making. It defies all logic in such terrible way that it's not even funny laughing at it. Practically every overused gimmicks in horror is rehearsed and in so much worse way than even the most mediocre films.
This is definitely the lamest case of recorded breaking and entering. The cast is large, yet none of them is actually likable. Everyone seems very obnoxious, even the characters meant to be sympathetic. The entirety of the movie is basically one stupid patrol of this supposed grim building, filmed by the familiar shaky cam and needless found footage antic. Its structure is so flawed audience can shuffle the scenes and it would barely matter since there's little continuity.
Worse yet, it tends to be comedic much more than it is terrifying, which for a horror is has none. The victims die in such agonizingly silly ways, and coupled with extremely bad acting, it's the shallowest attempt at horror in probably this decade. People would cross their eyes as though they are in pro wrestling, make stupid faces and roll around like they are impaired by epilepsy as substitute for fright.
It'd be funny to see these people die like in bad high school drama, but it only ends up being pitiful.
