Welcome Home is a bit of B Movie mediocrity is set in Todi, a gorgeous Umbrian town that V and I had the pleasure to visit in January 2002, shortly after the fateful introduction of euro banknotes. (An acute taste of the chronic pain to follow.)
In a more abstract sense it is set in the liminal space between Wop-o-philia and Wop-o-phobia.
The screenwriter clearly influenced by the particular paranoia peddled by those articles about Airbnb host-voyeurs, though perhaps not by the associated plugs for handy apps that largely deal with the problem.
This movie is deeply silly. There's a rabbit stew scene that is practically on the plane of self-parody. The female interest is 100% a male interest.
Yet the final 20 minutes or so up the levels of silliness to a point that almost redeems all that came before.
