Honestly, jp_mon , I think this discussion is comparing more the "perception" of whats either mainstream or popular in either countries vs the reality of what is actually produced/consumed.
And i think its fine to have those opinions, but to have a proper debate, we'd have to compare studio to studio, or format to format so that the comparison is more apples to apples.
It wouldnt be fair to compare something like Elegant Angel (which i would probably describe as closer to gravure or idol worship?) to a studio that is plot/storyline intensive.
take your example of Pierre Woodman.... back in the day i do believe he did more plot focused films.... then he moved on to his popular "casting" format where there is an interview, a foreplay, and a hardcore. But he also produces his "Wake up n fuck" series. which is a mix of amateur, raw, with light plot series.
A lot of studios houses are simply umbrella's for the diverse categories they offer to cater to a specific niche. If you are watching "BTRA (BigTitsRoundAsses)" and wondering "where is the plot?"... you arent fapping correctly, lol. BTRA is a glorification series focused on exclusively body parts, not the performer as a whole. If a viewer wanted to see the real person (or at least less of a "character") we'd choose a different format/series
I hope you dont take this response as me arguing or being negative of your perspective. I just think context and a change of perspective can be good in conversations.
I have actually been enjoying a lot of the feedback folks have been sharing about their favorite pasttimes lol.
