Excellent 'Other-side View' of Paedophilia

I think you make a lot of good points. In many instances, abusers do feel love for their victims (inexcusable none the less) and do not feel they are actually harming them even though they clearly are.

Also, let's not forget, it's not only "older men who fall in love with inappropriate young persons". Women are also abusers.

I disagree with your point 5. First, Ray's daughter is his wife's daughter but not his. She's his step-daughter. Second, Ray is not being authentic at all. Here's a different interpretion of the scene, that of a poster on the IMDB site:

"...[Ray]follows Una out and starts telling her again how special she was and how he's never been attracted to another young girl etc. He's clearly full of shit. At that moment, Una realizes that he's been full of shit for however many years. She realizes how stupid she's been for holding a candle for this guy, and she leaves, feeling disgusted..."

That's how I saw it too.

Hi, I have a totally different perspective from yours.
I have a feeling Ray was never in love with Una, he said that to not trouble himself and because she was very angry. He states so himself that at that time he was having a rough time, implying he didn't actually love her but was in a vulnerable state back then. Also, 3 months is a very short time to say 'love', he was infatuated with her (or, her youth and naivety), but i don't think he ever truly loved her.
I think his step-daughter being shown wasn't for no reason, I think it insinuates he married the woman because she had a young daughter, implying he's indeed a pedophile predator... but it is left ambiguous (for the viewer to decide). I think Ray was indeed a pedophile and all the excuses he tells Una are all bs, that predators usually use to lure their victims.
I think he only was after her youth and body, all the scenes of them in the past had to do with sexual matters (never shown connecting in another way/having a meaningful conversation) so I don't think he liked her in a deeper level. He's just a liar and pedophile.
Anyhow, I think it's up to the viewer to pick what lenses they want to see it with, take it at face value or look into it deeply.

I haven't seen the play so I can't really comment on that. I do wonder how different it is since it's written by the same guy that wrote the screenplay.

It's one of those movies that feels like it's trying to be way more important than it actually is. When you get right down to it, it's just a lot of explicit talk about a grown man having sex with a young girl.

A lot of the lines make it feel like it was written by a teenager and is fulfilling some male fantasy. Having Rooney say things like 'You touched my breasts' and 'You took out your prick and told me to hold it' or talking about if she came and saying things about how he 'f***ed' her all sound like a guy writing an erotic fantasy about a young tween girl.

A lot of it seemed to be filler. Was it layoffs that Peter was supposed to be dealing with? At first it seemed like that might actually come into play and intertwine with the Una storyline but it didn't. And what's with them trashing the break room? That made no sense.

For the most part, though, it was just them walking around a building having conversations in different rooms. Well, we're done with our conversation in this room. Let's wander into another room and start a conversation but make it about the same thing we talked about in the previous room. And then, it just kind of ended. But it didn't really end, it actually just stopped. As if they ran out of film. Actually they ran out of ideas. It's as if they couldn't figure out how to end it and just cut to black.

It felt like an indulgent, self-important film.

Funny thing, but when he starts up the driveway at the end, with his wife and the others having watched his interplay with UNA, it was obvious he had a lot to explain to the wife. I flashed on Dezi Arnaz, when he would say to Lucille Ball, "Lucy, you have a lot of s'plaining to do."

I felt the film took a daring and nuanced approach to a very controversial subject and the acting between the two main characters was very convincing. The direction of the film's ambiance creates a sense of tension & uneasiness throughout which I thought really worked.

Interesting. It's too bad that it required this long explanation to make the meanings of the film clear. They should have included more dialog to make motivations and feelings clearer. It looked more like Una was just determined to get revenge by being a homewrecker and thus became a cautionary tale, another Fatal Attraction.
