i agree with zacs, it is all a con.
people say they will switch off and stop watching, but they won’t – human nature and curiosity will see to that. what better way to boost voting (and cold hard cash) for the other contestants (refuse to call them artistes) than to keep this pair in the competition.
miss frank, that bloke last week and probably someone else like rachel were always destined to be out before the final, so what does it matter that these two are still in the comp ? they will go at some point, simon will decide when and i guess that will be once enough cash has been generated to determine that the “joke” has gone far enough.
if it enrages you enough to vote for the pair or another contestant, then generally speaking you have been scuppered.
