Tom Riley seems perfectly suited to the role, bringing an infectious energy to his depiction of a brilliant yet imperfect man—and it’s genuinely enjoyable to watch. He's supported by reliable performances from Eros Vlahos as "Nico" and Gregg Chillin as “Zoroaster,” along with impressive visual effects that explain some of the science and math behind his inventions, and a touch of sharp, even biting, humor as he initially has to gain the Medici’s confidence and then maintain it while constantly clashing with Pope Sixtus IV (played somewhat broadly by James Faulkner) and his assistant "Riario" (Blake Ritson). The show continued for three seasons, but the initial one offers a particularly fresh and compelling combination of desire, action, and political maneuvering. Elliot Cowan’s portrayal of Lorenzo finds him balancing his wife Clarice (Lara Pulver) with his mistress “Lucrezia” (Laura Haddock), while he attempts to stay out of trouble with the easily angered “Giuliano” (Tom Bateman), the menacing guards captain "Dragonetti" (Ian Pirie), and even his own father (David Schofield). The narratives are well-constructed, rooted in actual historical events (though not strictly accurate) and presented at a brisk pace as Leonardo constantly relies on his intelligence to survive. Riley manages to blend intensity with charm, giving viewers insight into the inner turmoil of this creative individual. It’s designed to be accessible for families, so while violence and sexuality are present, they aren't shown in a graphic way, keeping the focus on the often earthy and amusing writing. The first season focuses on introductions and conflicts with the Pope; later seasons shift more toward mystical elements involving the “fountain of memory” and his quest to find his mother. However, the final season seems to transform into an opportunity to showcase Riley and Ritson’s talents, losing some of the distinctive character that made the early episodes so appealing, instead opting for a dreamlike atmosphere with less engaging stories centered on rumored secret archives within the Vatican. It does eventually lose momentum, but the first season is worth your time if you appreciate well-written, fast-moving, and high-quality drama.
