I am not a gonzo addict
There are still studios that produce good "normal porn" that I enjoy. American studios like Digital Playground actually make good funny pornos. They are campy, cheesy and predictable - all in a good way. In fact, if the sex scenes are edited/removed, those porn movies can actually pass off as R-rated sex comedies of the National Lampoon, American Pie variety.
I think European movies lose out on this factor because of the language factor. Maybe multilingual crews not comfortable with making movies with lot of dialogue. So you end up with a Private style movies - hot girls, hot locales, hot and nasty sex (compared to American studios), but very little dialogue, not much of a plot and most importantly very little if any humor.
