I agree with you Farmor15. The main problem this year is the poor quality of the sewers.
Early on in the series the producers made the other mistake and had teams of almost professional level sewers. It meant that the tasks got harder and harder, I remember kilts and corsets, as a result the sewers were so concentrated on the task they hardly spoke to anyone and, again, it was a bit dull.
They then aimed at a real diversity of sewers and that works well, but they have now become too careless about sewing skills - and this lot just aren't good enough.
At the start they also had clear times for each round 2.5 hours for the first round, 1.5 for the second and 5.0 for the third. I think they should go back to that and design the projects to fit those timings.
