Lisa is not overated at all!, She was one of the very best!
After it's a question of taste the thing that she doesn't turn you on, doesn't make her overated, to me she has one of the hottest body and she was an exellent performer.
Back on topic here's my list.
Alexis Texas (i fucking hate her!), Jenna Jameson (the second one that i can't see), Keisha Grey, Abigail Mac, Christy Mack, Puma Swede, Phoenix Marie, Aletta Ocean all unattractive to me.
Some others (that i admit post time to time, because they have something that i like) Adriana Chechik (she do amazing scenes and i respect her, but she's just not appealing to me) Eva Notty (since her boobjob, before i liked her) and Ava Addams (i love her big tits! but she has too many moles on her body and that's a turn off to me)
I probably miss some names.
