This family-friendly drama is charming and has some heartfelt moments. While the central message of too much technology can be sometimes overbearing and monolithic, Team Marco remains appealing because of its spirited performances, strong relationships, and themes of gratitude, family, and learning what's really important in life. Technologically-engaged kids will enjoy and greatly relate to Marco and his underused friends, who all enjoy electronics, gadgets, and the next hot new thing. There are some minor moments of danger that shouldn't be encouraged, like riding in a vehicle with no seatbelt or eating foods that you might be allergic to, but these scenes are meant for comedic relief as Nonno tries to get Marco to loosen up.
Some stereotyping, however, brings the film down a bit. There isn't anything surprising about the depiction of Nonno as an older adult, as he's expectedly confused by modern technologies (new coffee makers, iPads, video games) and scoffs at other modern conventions of younger people, (social media, music). Racially diverse characters are few and limited to very small nonspeaking roles, and Marco's mother, Anna, doesn't get to do anything except be an aggrieved single mother who still cares who her ex-husband dates. Beyond fretting over him and getting Marco to clean his room and spend time with Nonno, Anna has no depth or role beyond that.
