Which version of The Wizard of Oz is the best?

The film of the Wizard of Oz 1939 is the best.

The story of the Wizard of Oz is basically known to everyone. It has also been remake countless times in history, but the most classic version is 1939, which won six nominations for the Oscar that year. Unfortunately, it is acceptable to lose the best film because of the blockbuster Gone with the Wind. When I was in primary school, I remember that the music teacher always showed this movie. Crossing the Rainbow was so classic that almost everyone could hum it. Before, it was always considered as an ordinary children's musical. Looking back carefully today, I find that his conception is as rigorous as a detective novel.
