The concept of the show was great, the execution was not.
The idea of the show being focused on finding the next great designer makes it appealing and I truly do think it started out that way. However as judges developed their opinions and biases about designers they quickly moved away from that. Based on their own comments during the fashion shows there should have been different outcomes at several points in the show. The most outright and frankly outrageous one is during the final episode when they all loved one collection and found faults with the other yet still crowned them victor. They should have been more forth coming at the beginning of the show that they don't care about finding the designer with the most talent, only the one who will sell best on Amazon. If they did they wouldn't have shunned the designers who showed creativity and innovation while praising the one who's looks the judges admitted to already owning variations of from other designers.
As much fun as the premise is and seeing what the designers created, the judges ruined the enjoyability of the show for me as I finished episodes frustrated with their decisions and reasoning.
