1. Extremely attractive women. If the women isn't close to being a world class beauty why bother? I doesn't matter how good she can fake it. I can look at average women at a mall somewhere.
2. Non-stupidity with the way the movie is produced.
3. The absence of douchebag looser male talent. (Which is hard to find) It's even worse if they act like asses in the movie. No bald headed talent. They might as well have a sign on them that says, "Yes, I am indeed gay like you all know I am". For that matter no gay or bi men, or tranny screwers from other films. No fat slobs. Nobody that looks like a twink. Even if the men watching don't watch it for the men in the movie they should at least look like somebody a women of that caliber in the scene might realistically want to have sex with to keep the realism so no old or ugly men either.
4. That the quality of the picture doesn't look like it was produced by a dropout from a local college cinematography department.
5. The complete and total absence of circus acts. The complete lack of anal also.
6. Women that don't act like bitches in real life, have some intelligence, aren't drugged out, know what they are getting into, somewhat enjoy what they are doing, and can at least fake it alright. The women must be good at seduction. A women with a good sense of humor is a bonus. (Also not very easy to find, but not quite as hard as finding absence of looser men.)
7. It doesn't have to be a written masterpiece, but it has to at least set up the situation to make it seem non-ridiculous, and be erotic while not losing sensualness.
8. Women start out clothed like real people unless the situation makes sense for it to be otherwise. The clothing must also be realistic.
9. They focus as least on the men in the scenes during sex as absolutely possible. Never ever EVER...EVER...under any circumstances focus on the guy's face during sex, especially pre-ejaculation
10. Cheesy lines are keep to a minimum.
11. The women are always treated well and there is a complete lack of misogyny.
12. The lack of gimmicks.
13. That it doesn't seem to come from the mind of some juvenile fratboy that needs to grow up or have a real man kick his ass or both.
14. The sound must match the action on the screen and not have some weird second or two delay like somebody sloppily put it together, ditto for having the correct names of the female performers in the credits.
15. The women can have makeup, but they shouldn't look like they have more on then most clowns do. Makeup should never run off during a scene.
16. There can be music in it but it should never overpower the actual sounds from the scenes. The music must fit the scene and not just be there for the hell of it.
17. Anybody outside the scene should never be heard or seen. The camera should never under any circumstances point at those people either. We don't give a shit about you, director/camera guy/some guy who happens to be on set for God only knows what reason whether you can accept that or not.
18. Interviews should only be done in the behinds the scenes footage. The women in them should try to be as honest as reasonably possible and not insult our intelligence.
19. The male talent in the scene should never tell the woman what to do either as part of the story or in trying to direct the action. The woman doesn't need to be told to, "suck my dick" for the fifth time.
20. There should never be any outside sounds that you can hear like a neighborhood dog barking or an airplane passing by.
21. In all outdoor scenes bugs should be avoided, and if they can't the scene shouldn't be done.
22. The men should never moan or grunt louder than the women do, if at all. They especially should never do the fake grunting right before ejaculation. It is enormously lame and destroys the whole scenes. Plus it makes us have the urge to kill you.
23. No spitting. You might think it's hot but it's not.
24. The women always finishes the job. It's very pathetic to have the guy waking off for a minute until the money shot.
25. Anybody who utters the phrase, "Dropping fucking loads" or something similar should be dragged out into the street and beat mercilessly.
26. There should never be any more than one man in a scene.
27. Men should never congratulate themselves on a job well done, high five somebody, or feel proud of themselves for something either in the scene or behind it. Again, it makes us have the urge to kill you.
So basically any movie out there I could really like only happens extremely rarely.
