does best christmas ever spoil santa

Yes, "Santa Claus is Comin' to Town" does spoil the ending by revealing that Santa was able to deliver all the toys despite the obstacles in his way. The story ends with Santa giving toys to all the children, but it doesn't leave much悬念 for the viewers. However, it's still a fun and heartwarming movie that shows Santa's determination and kindness, so I wouldn't say it's a complete spoil.
