Dark I can handle it it's done right. Stupid/nonsensical makes me crazy. Is it too much to ask for a SHRED of believability?
Jessica has the WORST friends. Not only do they take her to Tijuana without telling her, they don't even have enough common sense to stay together. You know, so they don't get drugged, or raped, or kidnapped. Way to make young women look stupid.
So Vale was supposed to be some kind of super secret agent? A cold blooded killer with nerves of steel? His gaping at seeing the scantily dressed women and going slack-jawed over a mansion was quite unimpressive. His "boss" is willing to give him $500,000 to kill this guy, but gives him no schematics on the compound and very little information about how things are run or what illegal stuff the guy is into. Sure, that's believable.
You want me to believe that Jessica has "dark" desires? Fine. But don't make her a fucking naive bookworm virgin! And don't make her attracted to the guy who just shot her BFF's boyfriend in the head! That is something that cannot be overlooked. Ever.
Jessica has been kidnapped, sexually assaulted, starved, and all she can think about is getting her orgasm? Really? This disgusting pig just forces her to perform oral sex on him and five minutes later she's doing the same thing to Vale and totally enjoying it? WTF? And of course Vale is all fine with it while he's getting his, but once he's done he's all, "this was wrong". You think? On top of that he keeps calling her darling. That's so creepy.
Jessica is "sad" that April doesn't want anything to do with her after everything is all over (and BTW, what happened to the other friend?). Gee, maybe because the guy you're mooning over KILLED HER BOYFRIEND.
And then a month after her ordeal ends, Jessica is ready to fly to Central America, by herself (!!!!), to meet Vale. And then they go sailing and joke around about how he kidnapped her. Oh, and she gives up her virginity to him. And asks him to TIE HER UP. That seems like sound decision making. Sure, he's a killer, but he's hot and got great hands.
