Basically your not a fan of videos without an engaging story line.
Yes, that's it. I guess that's why I went from regular porn to 3D videos and games. The only limit is the author's imagination, and I don't have to feel sad towards the actors.
To stay on topic, I find that Nick rarely has engaging stories, most of them have the feel of 00's porn comedies ; though when he dips his toes into heroines forced to bang vilains, his style works really really well.
His models scream "air-head bimboes", which by itself I don't find being a turn-on ; but when an intelligent and powerful character is turned into that, now it feels wrong, and so now we have something interesting.
