The mystery of the show is actually quite compelling. Spending a whole season (possibly more) with a family of characters and trying to determine which one is the killer. Given some subtle character development, this is the type of water cooler show that could really gain traction. Unfortunately, we get character development in the form of cringe worthy lines like "You drink!" "You do coke!" "You have attitude!" "I don't trust you!" Every character gets boiled down to their most basic cliches, from "drunk mom," to "obviously murdered someone."
It's a shame that with some more graceful writers this show could have become something really engrossing. As it stands, I honestly don't even care at all who the killer is. I don't care that whatshername died, and I don't care about these cardboard-cutout people's lives. I hope they all die, then are brought back to life, then die again. That would at least make for interesting television.
