The problem with this movie is that the premise is moot.
I personally have been dead for a period of time (granted, hours, not days), and was brought back to life. My body was brought to a hospital, not a house (as in this movie), and the work was done by medical professionals (not as in this movie). The year was 2005, ten full years before this movie was made.
Let's skip the discussion of the after-death and re-integration experience issue; leave it for another time and place. And, I don't want to write a spoiler.
The fact is I'm alive and healthy today, and I have all (or at least most) of my memories. I'm writing this review. Aside from a nurse welcoming me back as "a member of the walking dead - don't worry, there's more of you every day" (I'm presuming she was just being a wise-ass), there's nothing creepy or even dramatic about the experience. Profound, yes. But, as the nurse noted, this has become a daily phenomenon. There aren't riots in the streets, and people aren't agonizing over it. The practitioners aren't losing sleep about it or worrying about becoming pariahs.
Technically, the movie is OK, it's just that the premise is, well, way out of date. That effectively drains most of the real drama from the film.
