Sure I can get the concept. I can't name specific vids, but I have seen more than a few that fulfill that idea. Not a straight up meaningless pickup sex for fan service (the famous fap and gtfo fanbase), but either a (perhaps one-sided) romance between a man and woman or a plain seduction on a non-slut non-easy woman. There's a charm in it for sure. It's easier to work it with an "amateur" girl especially a girl I haven't seen in 10+ AVs (even in gangbang, bukkake etc) but it can work even with S-class idols. Maybe it's unfair to bring up a legend but Yuma Asami could pull it off with ease.This is already the seventh title in the series, featuring many of the main actresses in S1's catalogue.
Like i said, having the sixty minutes of build up is one of the main selling points of this movie. It gives the impression that this is an actual romance, and not just a flash in a pan thing like you get in many hook up movies.
My major concern is whether Rion can actually pull off managing to appear as though she is being filmed secretly. Her performance and acting normally isn't very good but i'm hoping that being in a more relaxed type of movie where she is being asked to simply be herself would help the issue. As you say, her major draw is
Anyway a great concept need to be carried out. I think SNIS-824 is a fail.
First I think the scripting/direction was weak, it's totally obvious that Rion was in on the fake voyeur game. So I was watching it and the whole time I was thinking this is bull shit anyway, so stop feeding me bad BS to try to convince me it's not BS. Instead make some good BS, it's not that hard. Yes I realise I'm rejecting a key point of this whole film series, and you already said you like the series, so let's agree to disagree.
Second, perhaps more damning... is that Rion herself is the problem. Last few vids, and the various discussion about Rion has sadly changed my opinion of Rion. Normally I am very superficial about AV idols, my priorities are clear: figures (esp. boobs), face, sex skills, acting, last is personality. With her goddess figure I was devoted to her no matter what, and hoping and waiting for her to eventually make better AV. Like, Julia in her early career was an inexperienced performer who relied on her figures to stay on top, but many (if not all) could agree she had improved greatly as a performer despite being a bit older and not as fresh. But for Rion, I am starting to lose faith in her.
Perhaps the problem isn't (just) S1, or the poor choice of vids, perhaps she's a particularly weak performer. Perhaps... even much much worse than that not as a performer, but as a person and a woman, suffers from some sexual dysfunction that she's not into it, and not able to fake it either. So what you see is what you get: a rubber sex doll with a fantastic figure, that's it.
