the concept of the show is a copy.
real? i don't know but i think they know they are being filmed so there might be some sort of act going own.
Not an exact copy, some similarities for sure but not a direct port. Plus the Osbornes basically was as dysfunctional as they come, not much depth at all. Likewise, the concept of filming people for the concept of reality has been around before the Osbournes came along.
