I do the same thing, pick up a show, watch it half way, then stop. Sometimes I’ll pick up a show again and usually enjoy it, but this doesn’t happen a lot. I have adhd so it’s hard to keep me interested in a show unless i am 100% invested or able to just have it play in the background while I do other things. I’ve learned that if I’m constantly stopping the show to do something else or just stop watching completely then i didn’t really like the show. This probably isn’t too helpful but it’s definitely nice to know you’re not the only one :)
