I'm not saying
Frozen isn't a great movie, just that it might not be the best conversation fodder for two people who don't know each other yet.
Why does a first date have to be ALL talking? Why can't there be both talking
and entertainment? First dates are about getting to know each other, but that can happen whether you're talking or not. Do you laugh at the same lines? Does she cry way too easily, or text during the movie? Does he leave his trash on the floor? Etc. It's not that you're studying the other person or critiquing them the whole time or anything, it's just that little things like that can tell you just as much about someone -- and your level of compatibility with them -- as their words.
I'm clearly in the minority here, but I think a movie + dinner/coffee/drinks (movie first!) is a perfectly good first date. I also think that a show + dinner/coffee/drinks is a great first date, and you aren't talking during those, either.
