You can have a good silly movie about space wizards that isn't taken too seriously but is really well made. People like to forget, but that's what Star Wars started as.
Star Wars started as a metaphor for the Vietnam war (with the US as the bad guys). In The Force has always been a lot of philosophy. Just because you didn't get it as a kid, doesn't mean it was silly.
And I say that as a trekkie who never really liked Star Wars but I see why people do and can appreciate it
