Heartwarming / Grumpy Old Men

• Despite the vitriol between John and Max, John firmly asserts that Max's son "Would make a damned fine mayor!"
• When Max goes to visit John at the hospital, the nurse asks if he's family or friend. After a long, introspective pause, Max replies, "Friend." Doubly heartwarming because they'd spent most of the movie at each other's throats, and Max had nursed a decades-long grudge against John for marrying his girlfriend.
• John and Max's feud stems from John marrying a woman Max had feelings for. Despite this, every mention of Max's deceased wife shows that he loved her dearly and remembers her fondly.
  John: If you'd married May, you never would've had Amy, and Amy was a good woman.
  Max: She was the best!
• Max has no time for Snyder, the IRS agent harassing John. Especially when he finds out that John's tax problems are technically not his fault, and due to a mistake by his ex wife. He tells him off to his face and gets his son to intervene on John's behalf to waive the late fees and loans him the remainder.
