Ok..at first I thought this was a terrible idea. But having seen Jon go back in,and those doors opening, a moment which was probably the best BB4 moment so far, Ive done a complete about-turn and think this is the best thing to happen to BB this year and the thing most guarnteed to make me start watching in earnest again.
Maybe it was a desperate move on ch 4's part, but desperation has worked for me.
