1.I freak out when the dildoes come out... or go in... I want real flesh there...FF
2. when flies land on them...the actors, not the dildoes but that would be bad too.
3. slow motion cum shots... rather see a spray in real time instead of fluid that looks more like nearly frozen elmer's glue.
4. bad outdoor lighting that looks like bouncing moving reflections off hand held reflectors which it probably is which makes you wonder why is the film crew moving and bouncing so much.
5. traffic noises, phones ringing, non-stop dog barking or sirens in the background although construction noises seem hot in a scene.
6. abrupt scene cutting from oral to penetrating without showing that beautiful moment of first entering.
7. women dressed as little school girls. just not my fantasy. Bad costumes in general and weird overdone makeup never seems all that sexy.
8. scenes with no build-up or indication the guy is about to explode but it happens all of a sudden and you wonder what was so damn exciting.
9. have to agree with #5 monsternmypant, it is all pretty bad and often gives a slanted, idealized aggressiveness that is often a shallow, uncaring and abusive representation leaving out all the finer aspects of intimacy.
10. when the trailers included are hotter than the actual feature.
