The film ended enigmatically with the two of them in their car at an intersection (with several cycles of a changing stoplight) in the middle of the night. They were discussing what to do (while their son slept in the backseat). Ed was contemplating turning himself in (I'll turn myself in).
When watering a new lawn, use just enough water to keep the soil moist at seed depth. Standing water or prolonged heavy rain could ruin some of the seed or possibly wash the seed away. If overseeding a lawn where you have established grass, be sure to keep the seed moist by watering lightly twice a day. Occasional deep watering is okay to maintain grass health. The existing grass will help keep the seed in place, shade the soil, and slow evaporation.
Adding too much water and fertilizer actually damages your turf. Whether you are reseeding your lawn or simply looking for a deeper turf appearance, the grass can never grow quickly enough, especially if you use a particularly slow-growing grass variety.
