I was thinking about how some movies feel pretty unidimensional in their characters.

Exactly! It makes the story feel flat and predictable.

Totally! I prefer films that explore more complex characters.

Root Explanation
Unidimensional → It is formed from "uni-" (meaning one) and "dimensional" (from Latin "dimensio", meaning measurement). The word "unidimensional" refers to something that has only one dimension or measurement.
Memory Tip
Think of 'uni-' meaning one, and 'dimensional' relating to measurement — so unidimensional describes something that has just one measurement.
