Couple decades ago, after watching a film at the cinema, two random girls at the exit:

• Girl 1: “That was a long film, what did you think of it?”

• Girl 2: “I loved it! But I didn’t understand the ending”

The ending was the plot twist.

I found that same movie slow and kind of boring… until the plot twist at the ending.

Since then, I always assume that either the reviewer “didn’t understand the ending”, or I “didn’t understand the ending”, so most reviews are useless.
