Personally, I like them and am in my third. I don't really care what other people think of them, good or bad, as I buy and wear what appeals to me. They are extremely comfortable to wear, and make a nice change from My more traditional/conservative watches.
I find that most people who voice a negative opinion of them have never actually worn one, and their view is based on aesthetics, which is fine but entirely subjective. To have a view on build quality, finish etc you would need to have examined one first hand, and the vast majority of (agenda-free) people who do would attest to the fact that they are extremely well made.
Hublot as a company are also excellent to deal with, and could teach many of the brands considered to be more premium a thing or two about Customer service.
With the introduction of their in-house movement they are also a forward thinking/moving brand. And whilst I cannot disagree with an earlier statement that they are ridiculously over-priced for the end product, this is surely true of all other luxury brands' non-precious metal watches. After all, how much does it really cost to produce a stainless steel sports Rolex, or Omega, or AP, etc etc?.
I have also found that Hublot residuals have firmed considerably over the past couple of years.
Just sharing my personal experience of the brand. Here is a quick picture of my latest one, please feel free to hate it....
