The most boring show on TV
That would be the Truman show. I think ratings would have dried up pretty quickly with that Leave it to Beaver world that was created. Look at reality TV and what is successful today, outrageous personalities and extreme situations rule the day. You could watch an hour long 'highlights' special once a year and keep up with Truman's life. Each day he does the same boring things, there is very little conflict at all (until Truman starts to suspects the truth).
As a metaphor for our relationship with and questioning of God it works well but as a comment on reality TV and celebrity ... not so much
