The Force Awakens is on the same level as Disney cartoons. Childish all around and very light-hearted. That's why a lot of people didn't like TFA: when they watched the other Star Wars movies, they were a lot younger, and so they loved those. But now that they're grown up, things are different. People who loved the Lion King as kids would most likely dislike a remake that was as cartoony, too.
So I thought TFA was shit, but that's because I like darker/more mature sci-fi. It was a good "Star Wars" movie, I guess. And sci-fi doesn't have to be serious to not be childish; look at Firefly for example, an extremely funny series and then a movie, but not childish at all.
Good thing
