This was meant to be the Big Brother that went 'back to basics' after last year's 'rich house, poor house' experiment. But we've had more 'innovations' than ever: first night nominations, double eviction night, housemate swap with BB Africa, injecting an extra housemate who has been able to watch the show beforehand, returning an ex-housemate (who also has been able to watch the show while they were out).
Of these, only the housemate swap added anything wothwhile and the rest have been disasters of one sort or another.
The strength of BB is the simplicity of the concept - lock a bunch of people up for 10 weeks or so, give it a competitive twist with the weekly nominations and watch what happens. The old saying 'if it ain't broke, don't fix it' applies here. C4 and Endemol have messed about with the format and come up with something that basically doesn't work anymore.
