It's better to avoid Blake so you're doing yourself a favor. Some of my friends here probably like it because the victim gets her well deserved revenge but I just didn't have it in me to watch Jennifer get raped repeatedly. (Yeah,it doesn't happen just once because hey,once just isn't traumatic enough!) Beyond that it doesn't do anything other films in this genre haven't.
As for "snuff porn" I understand most of it is fake but try telling that to me as a naive teen. lol. I really thought it was legit and that fucked with my mind for quite awhile.
