Most of the ones I've seen have had the same look (lighting and camera angles which are *much* more body-flattering than in hardcore; usually more natural-looking female performers), and they're basically hard-R -- lots of T&A, but no dicks, only fleeting glimpses at cooches.
Before the mrskin.com site was changed to prevent non-members from reading the full reviews, I was able to look up a few of these films. Apparently there is one director (maybe producer?) who is responsible for cranking a lot of these things out.
