Brad Pitt and Marion Cotillard fail to make sparks fly in "Allied". The much-anticipated team up that was rumored to extend off-screen did not equate to Humphrey Bogart and Ingrid Bergman's "Casablanca" in 1942.
Being the two movies are in World War II, there is much to compare between "Allied" and "Casablanca". In terms of the action and plot twists of the story, Director Robert Zemeckis carefully curated scenes in the movie. Unfortunately, the lack of chemistry between Pitt and Cotillard is pretty obvious.
The romance between the characters is crucial to the film since one of the takeaways the audience should have is about the complexities of love. According to Peter Travers of The Rolling Stone, people don't need to watch "Casablanca" again where "the problems of lovers really do amount to a hill of beans in this crazy world."
Another thing that seems to be a plot hole is the development and delivery of character question. On a review published on Pittsburgh Post - Gazette, Gary Rotstein pointed out that a suspense thriller movie needs "breadcrumbs laid, a character turns hinted and plot twists suggested" in a way that the viewer is kept on edge about the veracity of the scenes.
In line with this, "Allied" is not "Casablanca" and it does not have to be. With all the similarities between the movies, there are significant differences as well to be considered. Among these are circumstances, the nature of the conflict and even the romantic development.
Watching the movie in a perspective of a mature movie patron, one should recognize that this is not a remake of an older movie. But, an attempt to inculcate intelligent viewership through understanding the characters' thorny plots and getting to see conflicts that apply to real world scenarios, even if they are not exactly how you expected them to be.
