I'm really into movies and tv series that recently to keep track and rate them I've found this really well done app called MUST. I think its pretty famous right now, but if you don't know it I hardly recommend it to use. https://mustapp.com. Source: over 2 years ago

Here's a neat little website you can use to view the running times of shows. https://tiii.me/. Source: 12 months ago

Https://tiii.me/ suggests that Breaking Bad is 45 minutes shorter than BCS (though I'm not sure if next week's episode is factored in yet). Source: almost 2 years ago

According to Tiiime it's about 28 hours. Source: over 2 years ago

If I start now, I wonder how long will it take for me to watch this entire show or the series we have all had this thought about before starting a long series or show to watch. Well, think no longer about watching a show, Tiii.me website helps you exactly know how long that will take you to complete a series. - Source: dev.to / almost 3 years ago

I found this website awhile ago, which tracks TV shows and episodes watched (By runtime) a few years ago. I was adding season after season after seasons of stuff I watched then, and growing up.. And the total time before I stopped was like 4 years of watched TV. Source: about 3 years ago
