So kinda similar to Dead Set which was the what if zombies attacked the big brother house.

Somehow i totally missed this show. Going to check it out.

That sounds like an awesome concept, but since it ends on a cliffhanger and didn't get a season 2, I won't consider it.

I remember watching this when it was on. Interesting concept and the execution wasn't bad. Would have watched season 2 to see how it progressed.
