Movies are NEVER just “movies.” You’re kidding yourself if you think that. I have no idea if the critic of this movie is correct in this case, but every film has a message, sorry.
The message of most movies is “gimme money”. Of course all plot ares interpretable, and if they’re at all well written you’ll always be able to find real world parallels, but that’s not necessarily a message, it’s the result of realism.
