Rerun After Rerun
Rewatching a movie or TV series brings back memories we may not have remembered. Watching a movie a second, or a third time also gives us the chance to see things we may have missed the first time around. Usually, we wait a few weeks or months before re-watching a movie. The OP’s brother decided to rewatch a movie, solely because he was too lazy to take the disc out of the machine. It sounds like a pattern because when they were younger, he would stick dirty bowls under the couch instead of bringing them back to the kitchen and washing them (via Reddit).
