The romantic comedy has had its ups and downs like any other genre. But more than most, its films often find themselves so beholden to formula that they come across as uninspired retreads. Perhaps that’s why “Solo Mio” is such a breath of fresh air. Set around Rome and Tuscany, “Solo Mio” has a big heart, likable characters, plenty of well-delivered laughs, and more maturity than the standard-issue, run-of-the-mill romcoms of today.

Now don’t get me wrong, I’m not saying it’s “Roman Holiday”. But much liked that beloved William Wyler classic, “Solo Mio” features a similar charm and effervescence while being set to the same vibrant Italian backdrop. Of course the scenery is gorgeous and transporting without becoming a crutch. More surprising is the script which is brimming with humor, warmth, and pathos. But its biggest strengths are its two top performances from Kevin James and Nicole Grimaudo.

The movie comes from the Rhode Island filmmaking collective known as the Kinnane Brothers. Charles and Daniel serve as co-directors and work from a screenplay written by their siblings, Patrick and John. Kevin James pitched in with the script in addition to playing the lead role. Here he moves away from the slapstick silliness that has defined much of his career and gives us something endearing and heartfelt. It’s some career-best work.

James plays Matt Taylor, a 4th grade art teacher engaged to the sprightly love of his life, Heather (Julie Ann Emery). The two plan a storybook wedding in Rome with a lavish Italian honeymoon to follow. But on their wedding day everything falls apart when Heather leaves Matt at the alter. Heartbroken, Matt tries to cancel their big honeymoon plans only to find their “package” is nonrefundable. So he decides to stay in Rome, taking their honeymoon alone with hopes that Heather comes back.

As Matt tries coping with his sadness, he meets two nosy and intrusive newlywed couples at his hotel who take it upon themselves to get Matt back on his feet (much to his chagrin). There’s the well-meaning but overly assertive Julian (Kim Coates) who is celebrating his third marriage to Meghan (Allyson Hannigan). And there’s the henpecked Neil (Jonathan Roumie) who just married his therapist Donna (Julee Cerda). Yep, his therapist.

The oddball couples have good intentions. But it’s a fateful visit to a local coffee shop that turns things around for Matt. It’s there that he meets an outgoing barista named Gia (a fabulous Nicole Grimaudo) who notices he is a bit out of sorts. Gia has an infectious personality and an irresistible charm which doesn’t go unnoticed by Matt. But he doesn’t give it much thought. After all, Heather may come to her senses. And how can a man in his 50s start a new relationship from scratch?

But as Matt and Gia keep bumping into each other, a romance blossoms. Sure it’s a predictable turn, but the Kinnanes manage it unexpectedly well. It’s sweet without being schmaltzy and it’s playful without being silly. It’s a grownup relationship with authentic characters we genuinely care about. The lively Gia is a wonderful balance to the listless Matt. And when together, they come to life thanks to the natural, easy-flowing chemistry between James and Grimaudo.

As with any romantic comedy, there is a tension that threatens to uproot the central romance. Here it happens to be secrets that both are holding onto. Yet to the film’s credit, it’s handled in a refreshingly unique and mature way. It’s another welcomed surprise from a movie that speaks about relationships with such honesty – about how old ones can end and new ones can begin, no matter what stage of life you’re in.

“Solo Mio” may not cause a seismic shift in the romantic comedy landscape. But it does show that the genre isn’t out of gas just yet. It doesn’t veer too far away from the popular romcom blueprint. It simply livens things up by telling its own story rather than mimicking other films that came before it. James has never been better and Grimaudo should immediately be put on everyone’s radar. In the end, nearly all the pieces fall into place, making this a delightful, refreshing, and life-affirming crowd-pleaser.
