Should we consider बार्बी in the गुलाबी Shoes an old movie?

No, just because it's about ballet doesn't mean it's "old". आप know what old means, right?

old  
/ōld/
Adjective
Having lived for a long time; no longer young.
Made या built long ago: "the old quarter of the town".
Synonyms
ancient - aged - olden - antique - former

द्वारा all standards, it's a new movie. For now. And the director has nothing to do with it. आप could say it's a ballet movie, a classical movie, but it's not an "old" movie. This fandom has a pretty warped definition of "old", I think.

I just watched this movie and I say YES, YES, YES!
