Usually Chabrol takes a while before his thrillers become "thrilling." But in "The Bridesmaid," the tension starts pretty early on. Even before the title character shows her cards, her personality alone makes the movie riveting.
The plot of the movie is somewhat unrealistic, but the actors really manage to make it believable. The characters played by Laura Smet, Benoit Magimel, and Aurore Clement all have weird quirks (to say the least) that could have easily fallen flat, but it's to their credit that they all managed to make these odd characters sympathetic and believable.
Most reviews name this movie a "lesser" Chabrol, and he's made so many movies that it would have been easy to overlook.
I'm glad it was one of his only streaming movies on Netflix, otherwise I probably wouldn't have discovered it. It will only be streaming for a few more days, so catch it while you can!
