Subtle touches that rewards those rewatching
Spoilers about the ending, do not read any of this further if you havent watched yet.
At the end when Bob shoots Eric in the face, when you first watch this you have a similar reaction to what Nadia had. You think, Bob is a psychopath in his own way and he could snap at any moment. Eric Deeds showed his aggression and nutiness on his sleeve right out in the open. You knew he was unstable. But Bob just comes off as a kinda slow fellow that is living with and around shady people just because thats how his life turned out. His parents died and his only family left was Marv a loanshark and shady bitter person who lost his small piece of turf to a much meaner criminal crew. Bob seems to do cold things out of neccessity, so when you him he flat out murder a guy and show no remorse. It hits you how maybe you dont see Bob as clearly as you thought. When Nadia shockingly says "Bob, you just fucking shot him". Bob responds "Yes I did, he was gonna hurt *our* dog". That "our" sticks out as he is claiming a togetherness with Nadia and its disturbing as Nadia probably thinks: Im trading one mean psychopath, Eric Deeds, with another more hidden psychopath Bob Saginowski. She freaks, she thinks Bob or the Chechens are gonna kill her now. If Bob could coldly do this, who knows what he is capable of?
But if you're paying attention to the movie, Eric Deeds shows up to Nadias house and breaks in and waits for her to come home. Eric picks up Bobs angel (unaware it isnt Nadias) and places in on the other side of the kitchen table as if he is pretending its her sitting. When Nadia returns home, she doesnt know Eric is there and she sees Bobs angel on the table and she actually smiles picking it up and upon seeing its Eric in her house she quickly becomes moritifed. Her first response is "I dont want you here, this is my house get out". Eric, being the emotionally unstable nutjob he is, snapped and she shut down as you can tell she is used to being abused.
But at the ending, I noticed that after Bob killed Eric Deeds, he let Nadia go and he left her alone for some amount of time. He talks to himself about how some things can never be forgiven (I dont agree) and this is a way to let the audience know that Bob is capable of carnage, but he wants to be a better person and he is a christian. He gave Eric Deeds every chance to leave him and Nadia alone, he even tried to warn Marv not to do something stupid just because hes bitter that he no longer has that small piece of power anymore. Eric kept pushing, and Marv refused to listen. Which ended up with both being murdered. When Bob finally goes to see Nadia, he tells her "I know when you left the bar it meant for me to stay away from you. I understood that. But you didnt say it. If you tell me to stay away, I will". Nadias expressions show that she still loves Bob. THIS is a nice juxtaposition from earlier when Eric was in her house, she tells him to leave immediately and he wont do it (he's an abuser and psycho). With Bob, he stayed away from her for some time, left her alone, but out of Love and loneliness he showed up for another chance but he was willing to leave her alone again as long as she outright said it. This proves to Nadia that Bob is actually a decent man and not abusive. She had time to think about the shocking events, and to see that Bob really did leave her alone. Bob is dangerous, if he isnt treated right. This is an excellent call back to the beginning when they are both cleaning the dog Rocco after Bob finds him. When Nadia tells Bob is a pitbull. Bob gets nervous and says "thats a dangerous dog". Nadia points out that its not dangerous if the owners treat him right. The dog shouldnt be blamed for owners being bad to it. THIS is exactly Bob! Marv abused Bob's trust and innocence by getting him to help him Kill Richie Wheelyn. Marv then betrayed Bob again by getting Eric Deeds to hold the place up, knowing Bob was already having problems with this unstable dude. Thats why when Bob answered Deeds phone after he shot him. He just stared hard because he knew it was Marv that set this up and placed him in danger just to get back at the Chechens. Its not how an uncle is suppose to raise and treat their mentally slow nephew.
The symbolism of Nadia offering to fix Bobs angel figurine stuck out to me this time. Nadia helped to "heal" Bob as she was someone who herself had been hurt, and Bob literally became Nadias guardian angel.
And it was someone else that pointed out before, Rocco is a representation of Bob himself. A breed that is dangerous if mistreated by its owners, yet can be loyal and a wonderful companion to those who love them right (Nadia).
Such a wonderful and good film, I rate it up there with Slingblade as an interesting slow burn character study : )
