Somewhat misleading is the compilation's title, as the talent on display is short on superstars (no Jennas or the like), though we do get to see Adam & Eve's Carmen Luvana and Asia Carrera in action. On the stud side, featuring cameraman Jake Jacobs in one of his occasional sex performer stints is far, far from "legendary".
These throwbacks serve as suitable samplers, leading one to seek out the full-length original videos, so at that level it's okay.
