||This site is... well, just okay. It pretty much does what it says on the tin, and the preview allows you to see pretty much what's on it (although video previews are somewhat limited). It seems to have about 3 to 4 updates a week, each on about 25-40 minutes in length. Current videos are in 1920x1080, although about half from the back catalog are 1280x720. Each video page has a selection of features, including the trailer, streaming video, screencaps from the video for a quick preview, and a photoset for the shoot. Content is boy-girl, with some three- and foursomes, and girl/girl only as an intro to a threesome+ scene.
Overall, the quality and fidelity of the photos and videos seems quite good, although it seems like they take a bunch of rapid-fire photos to get the perfect shot - and then just dump them all in to the archive, leaving you to sort out the decent ones. Cinematography on the videos is about average, with static shots that sometimes linger for too long.
The general quality is better than most, with decent locations and okay lighting. Male models are okay to dubious, with a couple of decent-looking (albeit heavily tatted) ones. Female models range from moderately attractive to not so much, and plenty of fake tits to go along with the real ones. At no point will you be under the illusion that you are watching anything other than career porn actors trying to shoot a "softer hardcore" version of porn.
I suppose the main problem is that for a site called Passion-HD, the passion itself is somewhat lacking. You don't get a real sense of passion or connection between the actors at all, and the camera-work doesn't help that much, giving you a lot of static scenes that go on for just a bit too long. The sex itself is very mechanical and doesn't feel spontaneous or dynamic at all, just people going through the motions. There are a few videos where things "click" and the passion shines through, but unfortunately they are few and far between. And as the site is pretty much boy-girl scenes shot in similar locations with similar models, there's no real variety to change things up, with the result being scenes that look fine in short clips, but come across as very boring overall. Intro, oral, handful of positions, creampie/facial, done. Yes, it's classier than most (there's not much anal at all, mostly oral/vaginal without anything more extreme than very light bondage or sex that's a little rough), but it feels very much like a traditional hardcore production trying to make the transition to "glamcore" or whatever you want to call it without really understanding what people are actually attracted to in the genre and changing their models, direction and production methods to match.
So, if you want to watch a bunch of people who look very much like porn-stars have very staid (but fairly classy and not gross) porn-star sex, with an occasional standout performance, you might enjoy it. However, if you're looking for anything with an even passing resemblance to passion, you may want to look elsewhere.
