Its lacking a story. Ironically for a good reason. The stories used to often be whether the obviously best 2 or 3 would make the final, who would win , and who be derailed - by the person who wasn't as good but had the journey story, the joke candidate, the hunk vote, or the silly negative reason of the year for not voting for them. The people who supported the better canddiates then had someone to root for, and the people who liked journeys, hunks, jokes, and side stories with no logic were all happy too.
This year they have put 3 top females and someone not that far behind them, in, plus a clear male leading contender. They have spares for if the voting goes wrong. As 4 people could win, and 3 are similar, there's little to choose a winner on, and most people will end up backing someone who doesn't win - even if they vote on the dancing. The series doesn't have an improvement story, or journey, or a hunk becoming something more story, or even a Tom Chambers. There's lots of good dancing, but nothing thats not been seen before, and instead of a head to head race , we have a strong field of top runners racing side by side. .
There's also a lack of much else going on. There's no comic candidate this year - in a year thats missing comedy anyway with no Bruce. Alison isn't a Sergeant or Grant,or Hollins. Presentingwise, Claudia could be taken out with little lost. The interviews gain nothing, and are often bizarre, and the puns seem to come from Brucie's B team of joke writers. Brucie's dithering has gone, but so have his off the cuff remarks, and better jokes. Tess is filling most of the gaps well , and keeping it running smoothly , but a comic Brucie replacement alongside her, would have provided more. The judges have responded to their previous problems - provoking votes for the terrible performers, by realistic marking and more panto - by reducing the negativity and marking higher. Even Craig is now offering positives, where possible, , as well as better constructed negatives comments . Its lost its teeth though - so those who liked panto, or seeing innocents bitten, are deprived too.
Its probably also suffering from losing its old, liked , pros and any drama some like james used to create. They have found 2 or 3 strong new personalities, but its lacking its Vincents, and Ians,and Robins. Anton has become his own caricature, and Brendan has been tamed. Change isn't always good. it often just produces something worse.
The show has ended up with a stronger competition, that may run more cleanly . Thats good , because its less likely to end in an incredible win and undervalued brilliance. . When people don't care who wins, though, and the good started good, and its impossible to pick who actually is best, and you are unlikely to pick the winner , there's a big hole compared to many series. .
