I'll be able to see them for myself in 3 and a bit weeks, so will have a definite opinion then. Plus, I get that I'm a tourist, not a resident, so have different priorities!
I know aesthetics are important, and there seems to be an acknowledgement from some posts, that improvements will be made on the quality of the surface once the season ends, but in my opinion, providing there aren't sink-hole size holes where damage could be done, people will generally be more enamoured with the view of the beach and bay rather than wondering what shade of grey they are walking on. Yes, it mightn't be a perfect finish, but what's done is done, so I know looking down, shaking my head and sighing won't make it change. I'll just look up and enjoy the reason I go back to PP - the view!
As for the seats, they are different - so obviously some people won't like them. Others will. To me they will provide somewhere to sit for a minute and have a break and a drop of water. I've sat on worse! Again, I won't concentrate too much on the shape of my seat, when I'm looking at the view. If anything, they get people talking which has to be a good thing!
Anyway, I reserve the right to change my opinion in 3 weeks when I see them, however my hope is that I probably don't even notice!! There are better uses for my eyes.
