I saw this movie when I was a little girl. And I have enjoyed it every time. Sure the graphics are a little cheesy, compared to now, but back in the 70's it was great. I saw it in the original Spanish version only and thought it was wonderful. That was how I remember my Christmases were with my family - magical. Santa Claus was amazing and I couldn't wait for him to come back each year.
If you have a child/children and speak Spanish, bring them up watching this old fashioned version of "Santa Claus". It's a different version than we are used to today, but who says there is one way?
It's a fun movie to watch. It teaches children good vs. bad. I don't know how the English subtitled version is or if there is an English one of this, but the Spanish is the best. Enjoy and Happy Holidays! Feliz Navidad!
