Matt Singer’s review published on Letterboxd:
Barb & Star Go to Vista Del Mar isn’t a movie, it’s a wavelength. You either get on it or you don’t. I’m sure some viewers will complain that Barb and Star are so quirky and chipper that they’re annoying, or that the film’s comedy is too bizarre and random. Take my advice: Cut those people out of your life. You don’t need to associate yourself with anyone who is that wrong about something this important.
