Yup. George said the original six films were also aimed mostly at younger viewers. There's been a lot of talk about this being aimed at older kids, about being almost a PG-13, but that's probably just a lot of hype and/or an attempt to deflect critics that say he's making violent entertainment for the kiddies.
It's absolutely aimed at a younger audience. I'm not saying that's a bad thing-- heck, I've watched every episode of Transformers: Animated and (I think all of) the Spectacular Spider-Man show.
Jedi_master_sal pretty much nailed it-- strike the nicknames from the film, or at least the ones Ahsoka comes up with, and I'd say you're in a lot better shape. If you watched Droids since you became an adult and liked it, I think you're gonna like the movie a lot. If you think it sucked... well, maybe not so much.
