Logan ★★★★

Normally I give a better than average action movie like this (or like Avengers: Infinity War) a rating of three and a half stars.

However, sometimes such 'a better than average action movie' contains an element, a moment, an idea, a sequence, that deserves an extra half star.

In Avengers: Infinity War it was the surprisingly dark ending, in Logan it is the wonderful Shane quotation.
