I’m not sure why this name is rated so low. I personally had no idea about the Superman association, and I reckon most people wouldn’t either. I wouldn’t even pause if I were introduced to a Kalel irl today. I think it has an Arabic air, what with the dash between elements. The spelling Kalel is more American. I think this name is a contender!
This name is ridiculous, especially on a real child. Poor Nicolas Cage's son has to live with this ghastly name. (Maybe he'll change it when he's older.)
