The filmmakers did not understand some of the usual visual language of cinema with how they present this ex-girlfriend. For example, when we first see her, she is doing her make-up with her friends. She's in the middle, and she's the tallest. This makes her seem vain and imperious. Later, we see her combing her hair while talking to her husband, but not looking at him. This makes her seem cold and witchy. The actress is very beautiful but very cold looking, with very sculpted, unnatural features. She almost never smiles. Basically, she seems like the mean girl in the '80's movie, or one of those girls who was mean to Toni Collette in Muriel's Wedding.
They don't make her likable or inviting, is what I'm saying, so we can't relate to the creepy guy's fascination with her. Actually though, they do seem made for each other, because just as she is plastic and icy, he is sinister and ominous. Come to think of it, they are very like Heathcliff (not the cat) and Catherine from that Kate Bush song Wuthering Heights.
Meanwhile, his other friends cope with their own earth-shattering, soul-destroying problems. One of them is a tiny, babbling man who does everything he can to irritate the crap out of everyone around him. He not only is a salesman trying to pitch ideas, but he never ever stops talking. He is stunned that a girl dumped him for a quieter friend of theirs. When he is not badgering rich people about investing in his simple ideas, he is picking fights in public, walking around with a shotgun, and splashing people in the pool.
(What he acts like is that little dog from the old Warner Brothers Cartoon that always ran around the bigger dog, talking nonstop about what great pals they were.)
Babble Guy's ex-girlfriend who dumped him for Quiet Guy just wants to get married. Quiet Guy apparently keeps putting it off or something. He may or may not be waiting for Babble Guy to stop holding a grudge, it's not too clear. There isn't any more to their characters than that, so they are easy to describe. She pressures him about getting married and complains about him, and he tries to fend off Babble Guy's random physical assaults. Babble guy is tiny but feisty, like a kitty-cat.
A third friend is a man who looks just like a hobbit, or like Lars Ulrich. He is an alcoholic, but not one who does any of the problematic things that real alcoholics do. He doesn't stink, pick fights, vomit a lot, have health problems, annoy people, lose money, fail to show up when expected, wake up in strange places, be mean, cry a lot, get into accidents, or any of the other things alcoholics do that make them impossible to be around. All he really does is take naps on pool chairs or porch swings. So, he is a cute, cuddly alcoholic who might smell like Downy fabric softener. Luckily for him, a perfect, kindly, beautiful white girl decides that he is exactly the man she's been looking for, and she walks around their little town with him a lot. After he responds to her sexual overture with a tearful confession, all of his mental problems lift from his shoulders and drift away like a cloud on a summer's morning.
This movie has a very nice musical score, and a pretty scene with some fireflies. I was glad that they didn't set that scene to the song "Fireflies", so kudos. That scene unfortunately ends in a zoom-in close-up of Rapist Guy's face, as he apparently realizes something creepy, and he gives a terrifying serial killer smile at the camera. They cut to another scene before he can break out into a maniacal laugh. (Oddly, when you find out what he figured out, it's just that he and the ex-girlfriend aren't right for each other.)
If you want to see the tough guy who always beats the crap out of everybody on Leverage be a nice, sweet person, he plays the Ice Woman's new husband.
