I did. It was kind of a disaster because this isn't a kids movie really at all, but they suffered through alright. I wanted to go so bad, and it's cheaper to drag them than hire a sitter. It's not that it's gory or violent or anything; it's just that it's crazy boring. My son asked me where all the woodland sprites went. And it's true: this is 99.9% woodland sprite free, which is not usual for Miyazaki.
I really can't name a single Miyazaki I don't enjoy watching or rewatching, if I'm in the right mood. And I'm pretty sure I've seen them all. (Actually I just thought of one right this second: Porco Rosso, I've only ever seen once, and didn't like that much)
Mine went through a period of watching Pom Poko daily, for what seemed like months. I was a bit over it back then, but I still love it, now I've had a break. I think my all time favourite has to be Totoro, my daughters were 13 and 4 when I got that DVD, and it so perfectly captured their relationship it was magical. Also, catbus!
