After looking on Fuji 800Z and Provia 400X on Flickr, perhaps I'm not seeing what you're saying, B&Wpositive.
I see a few photos where there is severe overexposure, blowing out any contrast and de-saturating colour. I see some where the colours look badly skewed. I also see some that are very underexposed and hard to make out anything. I also see a couple where there was deliberately digital de-saturation implemented. In short, I see a dog's breakfast of results.
In the end, there are three considerations to allow:
1) Many film photographers are in a constant learning process, some further along than others (while some just don't progress beyond a certain point);
2) Some photographers don't hew to a notion — or an agreed one — of "traditional" methods, as you expressed;
3) Style is highly varied between different photogs — just like other artistic media — and one's saturated, underexposed, contrasty shot is another's undersaturated, overexposed, flat shot.
Personally, after seeing some of Jose Villa's work — his name is new to me — I must say that I really do not appreciate his style, one I would call "milky and washed out". But again, this is entirely a subjective call. Clearly his style resonates with the wedding client crowd, and rightly so, his formula appears to pay off. When working with colour — more specifically, when working with reversal colour — give me someone who underexposes by 1/3rd or 2/3rd stop in order to saturate colour and give shadows a rich darkness. I really don't like seeing blacks that end up being greyish and highlights which look like white crinoline was draped over the lens.
