The concept of Chiara Mastroianni living under the shadows of her father (legendary actor Marcello Mastroianni) and exploring the world with actors playing themselves is a interesting concept to explore about reality, nepotism, Italian culture, and community. There are some strong moments that prove of it's good use, but as a whole, filmmaker Christophe Honore crafted something that's just decent.

Provided with good performances, certain good dialogue and structures, Marcello Mio falls into the category of failed meta commentary narratives because it struggles to understand what the tone, the narrative and style the movie really wants to focus on and becomes a habit of being a bit messy. Nevertheless, there are some good dynamics between the characters playing themselves, including some good humorous approaches, and costumes. However, things could have been better.
