This is the way. Show your kids the things YOU grew up with. Instill in them an appreciation and nostalgia for stories made before their time, before we got "spoiled" with all this CG and special effects-laden crap. It'll make them far more open to partaking in and enjoying media made across multiple times, which is sadly missing in a lot of people these days, who'll condemn anything made at least seven years ago as "old and outdated" and refuse to touch it.
