Bruce Willis is a name associated not only with iconic action films like Die Hard but also with science fiction. Just think of 12 Monkeys, The Fifth Element, or Armageddon—all released in the '90s.

About the Film
"Cosmic Sin" takes us to the 26th century, where humanity has colonized other planets and encountered a hostile alien race. Bruce Willis plays retired General James Ford, who is brought back to service to prevent an interstellar war.Criticism
Viewers and critics are unanimous in their verdict: "Cosmic Sin" is a failure on all fronts. The film even "earned" the Golden Raspberry Award in the category for "Worst Bruce Willis Performance in a 2021 Movie." However, the organizers later withdrew the award upon learning of the actor's illness (frontotemporal dementia). But, as they say, the damage was done.Here are the main criticisms of the film:
Meaningless and cliched script: Viewers complain about the lack of logic, predictability, and abundance of clichés:Some note decent special effects, yet they are overshadowed by a "terribly written, meaningless, and incoherent plotline," as well as terrible acting and weak dialogues.Reviewer Cpt_Acid from 'Imdb'It feels like no one wanted to make this film, but someone forced them to do it. The script is full of clichés, as if you initially didn't want to write it but were compelled to. I don't see how they [the filmmakers] are making money from this, no matter how insignificant the investment. What's the point? I would love to know.

Mismatch of setting and time period: The film is set in the 26th century, but viewers are shown scenes with people driving pickup trucks resembling those from 2021:
The film's plot doesn't stand out from other movies of the same genre. It feels like it was made just for the sake of making it.Reviewer sumtim3s00n from 'Imdb'It's all happening in the same kind of city as today. Gasoline cars, guys in grunge-style plaid shirts drinking beer, and everything around them — it's about 2005. Nothing has changed except for a CGI spaceship. Everyone uses regular guns with gunpowder-driven bullets and gasoline. They're still using incandescent lamps.
Opinion
"Cosmic Sin" is a vivid example of how not to make science fiction movies and how not to bring legendary actors back to the screen.It raises the question: should Bruce Willis have agreed to this role? Wouldn't it have been better to preserve in the audience's memory his image as a tough guy and a hero of cult sci-fi films? What do you think, is it worth it for actors to return to the screen in controversial projects, risking their legacy?
