How many times have you been awe struck by the actress on the cover - only to be disapointed by her fake moans and overacting???
Sure, there are a few perfect 10's that look good and get really into the scene, but they are kinda like unicorns.
I'll take a 8 or 9 (even a 7) in the looks department if i can get a 10 for intensity.
I would list my favorite actresses, but I doubt they'd appreciate being described as anything less than a 10.
