Nothing wrong with going to a "kids' movie" without kids. We do it all the time. We try to stick to weeknights or weekdays ('cause parents have to work), and avoid opening weeks, but for the most part it goes okay. (I say "for the most part" because there are some really obnoxious parents out there who can't control their kids... we all pay to see the movie, people, not to watch your little darling run up and down the aisle hollering at the top of her lungs.) Never been looked at funny by anyone - indeed, there are often other unaccompanied grown-ups in the audience.
