It's the paradox of choice - the more options you have, the harder it is to commit to something new and unknown, and a familiar series guarantees you won't be disappointed. An hour of deliberating drains your willpower, and eventually your brain just grabs the tried-and-tested option to avoid the effort. Plus Friends works as background noise - you don't need to pay attention at all, you can just put it on and zone out after the day.
I've noticed the same thing about myself - you sit there scrolling, and half an hour's gone before you know it, still searching. At some point your brain just gives up: you've burned through your decision-making energy and autopilot kicks in. It's easier to fall back on something you know works than risk spending the evening on something you might hate.
There's also the comfort factor. When you're watching Friends for the hundredth time, there's no stress - you know what to expect, you can just relax and not have to think too hard. A new movie demands your attention, needs you to focus, and you might not get into the plot from the first few minutes. After a rough day, that feels like too much work.
Try cutting down the selection time with something simple: pick your movie ahead of time, before you're sitting in front of the screen. Or make yourself a rule - if you can't decide in 10 minutes, watch something new by default, even if it feels a little risky. It's easier to just try something unfamiliar once than to regret spending an hour scrolling later.
