August Sparrow’s review published on Letterboxd :
This movie takes place primarily in a single location and is 90% dialogue. Fortunately, the script is compelling and keeps you interested for the length of the movie. Like the characters, viewers aren't sure if the protagonist is telling the truth, making a joke, or crazy. As the film progresses, the characters make their own opinions and so can we. Most of the ensemble cast is good, but there are a few performances I found oddly distracting (like they were acting in a stage play instead of a movie).
Final Grade: C+
