Come on now, nobody is holding a gun to your head to make you buy their product. I do agree that the only change we've seen is not the product itself, but the more competent post-processing by users. That is, if we ignore the introduction of a 120 format of the product, which I guess was/is meaningful to quite a few.
As to the product being 'bad' - I'd call it 'unique'. It does something that no other CN film on the market does. Whether you like that is entirely personal. I've shot only a few rolls of this, but whenever I show the stack of prints made from them, people invariably recognize something special is going on that works very well for some images (but definitely not all). If you understand and exploit this film's inherent characteristics, it's a unique and powerful photographic tool that has no equivalent in the film domain. I frankly hope and recommend that if Harman progresses this project towards a more conventional, masked CN film, they keep producing small batches of Phoenix as we know it now.
