That's basically how I was. Honestly, the reason I enjoy movies nowadays isn't really because it's my thing, but because my wife is always so excited to show me the movies she likes, and I can't help but enjoy myself when it's making her happy.
I rarely watch movies on my own, or with other people besides her, but when I do, it's usually because I think it'd be fun to tell her all about it, and maybe watch it with her too.
I'm also bigger on reading, but I have really severe, unmedicated ADHD, so I can't sit down with an actual book for longer than a few minutes. Gotta have pretty pictures, like a manga or graphic novel or something (and even then it's hard.)
