This article also makes a good point – internet users download more clips than porno movies, which means that dialogue and scripts are thrown out the window. And, quite honestly, if you look at the past few movies made in the 2000s, then you’ll notice some mediocre acting and poorly written dialogue. And whose going to pay for an acting teacher?

Although I may have to disagree – you can still care about a character and pitch a tent too. The examples you cited are also examples of writers who didn’t care enough about their characters (or, possibly, the plot) or were so involved in the sexual content that the characters and plot become 2-dimensional. There are definitely sexy movies that showcase unforgettable characters performing some unforgettable sex scenes.
