I'm a big fan of the "GPS Theory" when you miss a turn, your GPS doesn't judge you, it recalculates. No matter how many detours you take, it finds another way forward. Life works like that too. You'll make mistakes, but your destination doesn't vanish. The route just changes.
Six Feet Under (2001–2005) begins with a death and ends by reminding you life is the point. Every funeral becomes a window into the Fisher family, and few shows have understood grief, love, and growing older with this much honesty.
