"tv show" leaves it very vague, if it's any genre, I think it's The X Factor.I've rewatched Tokyo Ghoul 4 times and Death Note maybe 6 or 7 times I watch it when I'm falling asleep and don't want to fall asleep and miss out on a show that I'm into at the time I find it hard to rewatch other shows though I just don't find them interesting enough every time I rewatch them I find something new that I didn't notice the last time.
But if you're talking about anime, I'm torn between Naruto (Hajime and Shippuden) and Sword Art Online.
