Matthew Vaughn returns with a new film, 'Agamemnon', after three years.

The protagonist of Agamemnon, 'Ellie' (played by Bryce Dallas Howard), is a bestselling novelist. She is also the author of the spy novel 'Agamemnon', which is also the title of this film. One day, real-world intelligence agents come looking for her. He tells her that the story in the novel Agamemnon is actually happening in the real world. Ellie must work with these agents to complete the ending of Agamemnon.

Matthew Vaughn's films have been praised as A-list movies in B-list disguise. Their scripts and direction are full of whimsy, but they possess the A-list quality and mass appeal. Released in 2015, 'Kingsman: The Secret Service' was a box-office success, grossing over $400 million on an $80 million budget.

In fact, Matthew Vaughn's career has been on a downward trend since the success of 'Kingsman' in 2015. 'Kingsman: The Golden Circle', released in 2017, was a box-office hit similar to its predecessor, but required a larger budget and received negative reviews from critics and audiences alike. The Kingsman prequel also failed to capitalize on the series' unique strengths, leading to negative reviews. While his previous films were A-list films disguised as B-list, his more recent works have been labeled as truly B-list.

Critics who saw 'Agamemnon', which opens in the first week of February, say that it still showcases Matthew Vaughn's signature strengths. The film features fresh, whimsical action in the latter half and just the right amount of comedy to give the film a sense of energy.

Interestingly, the film is a film within a film. Ellie experiences adventures in the real world and writes Agamemnon, which unfolds its own story within the novel. This fictional world, according to reviews, exhibits Matthew Vaughn's more exaggerated, whimsical style.

The actors' performances have also been met with positive reviews. Henry Cavill plays the protagonist of the novel, 'Agamemnon'. True to his past performance as Superman, he delivers a strong performance and action sequences in this film. Bryce Dallas Howard also delivers a flawless performance, and her chemistry with her cat is particularly noteworthy.

However, critics have pointed out that the middle part of the film is somewhat dull and that the action sequences may feel a bit childish, as the film is not rated R.

Matthew Vaughn's 'Agamemnon' opens in theaters in the US on February 2 and in Korea on February 7.
