It's about as real as WWE wrestling. The producers manipulate the whole thing to create fake drama for the dummies that watch it.
I actually know someone who knew Mike Thalasittis-nicknamed "Muggy Mike" in the programme - who was painted as a womanising bad boy. Apparently he was a really decent and sensitive guy in real life, but the manipulated scenarios and editing made him look like a massive cunt.
A fascinating claim to fame well done.
