Which series can you watch over and over again and why?

For me it's My Beautiful Man. I never get tired of it because every time I watch it, I find a new detail that I haven't noticed before. The cinematography of it is also just beautiful to watch (and rewatch). And lastly it's my comfort show because I love relationships that are all about adoration and obsession, I love the "you're the only one for me" type of love.
