I mean, read this fucking wiki summary.
"Patrizio Sr., hoping to open his restaurant, has resorted to illegal bookmaking . Having bet most of his money on a Philadelphia Eagles game, he asks Pat to attend for good luck. So, Pat asks Tiffany for time off from practice to attend the game. She gives him a typed reply from Nikki, which cautiously hints they may be able to reconcile. Before entering the stadium, Pat and his brother Jake get into a fight with some racist fans and are hauled away by the police. The Eagles lose the game, and Patrizio is furious.
When Patrizio claims that the Eagles lost because of Tiffany being involved in Pat’s life, she refutes his allegations by pointing out that the Philadelphia teams had done better whenever she and Pat were together. Convinced, Patrizio makes a parlay with Randy: If the Eagles win their next game and Tiffany and Pat score five out of ten in their dance competition, he will win back double the money he lost on the first bet.
Pat is reluctant, so Tiffany, Dolores, and Patrizio conspire to persuade him to dance in the competition, telling him Nikki will be there. Noticing that the letter from Nikki also refers to “reading the signs”, a phrase frequently used by Tiffany, he realizes that she wrote the letter.
Tiffany, Pat, and their friends and family arrive at the competition on the night of the football game. Tiffany despairs when she sees Nikki in the audience, invited by Ronnie and his wife [Tiffany’s sister] Veronica. They want Nikki to lift her restraining order on Pat and give them the chance to reconcile. Tiffany starts to drink heavily at the bar.
Pat finds Tiffany moments before their dance and drags her onto the dance floor. They begin their routine as the Eagles defeat the Dallas Cowboys. After their set, Tiffany and Pat receive an average score of exactly 5.0 points, amid cheers from friends and family and confused looks from the crowd.
Pat approaches Nikki and whispers into her ear. When Tiffany sees this she runs off, so Pat leaves Nikki and chases her. He hands her a letter, in which he admits to knowing she forged the letter. He confesses that he loved her from the moment he met her, though it took him a long time to realize it. 
They share a kiss. Patrizio opens a restaurant with the money he has won, and Pat and Tiffany begin a relationship, no longer wearing their wedding rings."
I mean, what the fuck is this bullshit? The dumbass typed letter either A) Makes the lead look like a fucking moron, or B) Assumes the audience is a drooling mass of idiots. The bookie for some reason takes a parlay on a FUCKING DANCE CONTEST. Why is Tiffany blamed for Bradley Cooper getting into a fight before the Eagles game? Fuck if I know.
None of this, not a single fucking thing in this movie makes a damn bit of sense. I guess Richard Brody and I are the two sane people on the planet.
“Richard Brody found Linings perhaps to “be the year’s most artificial film” and “the plot […] utterly ridiculous.”[68] In a rare step outside the magazine’s typical practices, Brody revisited the film and wrote a supplementary review, once again condemning it as having “no characters but sets of switches, each of which has a binary set of options and all of which have to line up for things to come out right.”[69] Brody wrote, “I’m finding it hard not to make fun of the film’s highly constructed and narrow-bore array of givens, of plot points and their resolutions.”[69]”
I love that he went back with the idea of "How can so many people love this shit. a fucking 81 on Metacritic and 92 on RT? Better go back and give it another watch and make sure I didn’t miss anything… NOPE, still fucking garbage. Probably more so than the first time.
