I totally agree with everything in this thread. Len is an absolute walking inconsistency when it comes to the contestants.
Like others have said, I feel like he often marks on expectations, which is plain ridiculous and unfair on the better contestants. It's not fair to give someone a 9 for improving endlessly, but then giving a talented dancer the same score for a better dance, because they didn't improve on his expectations.
To be fair, Craig is the only truly fair judge in this. He'll note any improvement, but still won't give a "7" worthy dance a "9" because he was pleasantly surprised by how much better it was than he expected.
Oh, and also Bruno has been less annoying score-wise than in past years. He's sometimes a bit generous, especially with good dances, but in particular with the weaker dances he has been fairer than he has in the past.
