Overall I like Nina so far, but this video petered out after awhile-a few scenes I had to fastforward through, I found them unbearable-they were just too slow, useless, and/or corny. There's a few scenes in the dance part that seem to never end where they're all dressed in their aerobics clothes doing all these stretches as Nina talks about dancing, etc-BORING (and stupid). Not to mention you can see the camera people several times in the sex scenes which didn't help the mood for me. I learned a couple new things, but have seen better. One scene between a mismatched couple was way overdone and so fake it was comical.
The title promises seduction but doesn't deliver. It starts with people ALREADY naked -- that's foreplay, not seduction. The opening feature is mostly Nina working on another woman, who was very attractive in a nonglamorous way, but that could be a turnoff if you're renting this to show a woman in your life how to act sexy.
