Pretty classical question, curious to see what you all think.
For me, it’s Pacific Rim. It is mostly about giant robots fighting huge monsters, but the the psychological treatment of the characters is more refined than someone would expect for this kind of movies.

And the intro is very poignant scene, again, not something you would expect in this kind of movies.
The Road to Wellville (1994)
https://imdb.com/title/tt0111001/?ref_=nv_sr_srsg_0_tt_8_nm_0_q_road%2520to%2520well
It’s a historical farce about Dr. John Harvey Kellog (brother to the cereal mogul) and his bizarre obsession with health. Ridiculous cast for it’s time, including Matthew Broderick, John Cusack, and Chief Miles O’Brien (or Colm Meany, if you will).
