Sometimes, when I have a few days off and the weather is bad. It's pretty much my gf and I's custom to binge watch tv shows (Japanese or otherwise) when a strong typhoon is passing. On regular evenings - nope, not since college.
One thing I like about watching whole series in one sitting is that it prevents me from getting distracted halfway. When I miss an episode of an ongoing drama due to some real life circumstances, I often fail to remember to catch up and end up dropping the show, even though I was enjoying it. When binge watching something, I will only drop it if it's actually bad.
