What's the point?

Rating: 4/10 (31 January 2020)

The entire movie is about cracking the Enigma machine and not even once the movie REALLY explains how the machine works, which is really interesting of itself. But I can get where that comes from, it may be too complex for the ordinary viewer to understand in a short amount of time. But then what? what's the point of the film? Raising awareness to gay discrimination? Then why only mention it at the end? I feel like the movie had no point to it.
