Czeresko wins. Save your time.
Like other commenters, I was looking forward to this show that blended the creative process with the technical mastery of the glass blowing form.
Katherine Gray made the show about social justice rather than mastery of the craft. She held a thinly veiled bias against other contestants, while repeatedly complementing Deborah Czeresko on her creative choices and bravery (even when many of her pieces were crude in execution).
The show could have spent more time going into the technical aspects of glassblowing. Janusz Poลบniak created pieces in one of the competitions that were absolutely elegant. I would have loved to have seen the methods he used to create them. They skipped over the process of mixing color into glass almost entirely.
Sadly, the show began increasingly pushing misandrist views over artistic interpretation, technical execution, and professionalism (the three criteria the show supposedly judged on). The producers clearly wanted Czeresko to win. I don't know why. Czeresko felt it necessary to attack other contestants for their technical proficiency (and supposedly lack of creative ability). Instead of graciousness when others won, she mocked them for being pedestrian. She was as unappealing a winner as could be imagined, only slightly edging out Katherine Gray for being unlikable.
