Kids, especially in an era when movies such as STAR WARS were still extremely uncommon, aren't the pickiest critics. Give them a few spaceships, laser guns, and lightsabers and they're happy.
I *loved* THE EMPIRE STRIKES BACK when it was first released in 1980; my dad, who had liked A NEW HOPE, found EMPIRE boring overall (he liked the Hoth battle sequence, but Yoda training Luke bored him to sleep).
