There is less than zero chemestry between the two leads, and one begins to wonder whether the actors even like each other or are just tolerating one another for a paycheck.
Allee tells Greg/Ethan that she and her brother, Nick, came to live at the vineyard with their Grandparents when she was eight years old and her brother was five. Why, then, is there such a huge gap in age differences between the female lead and her brother? The female appears to be roughly 40 (and, indeed, the actress was 39 or 40 at the time the movie was filmed) and the brother appears about 22, with that actor having been probably 27 at the time of filming. Nick might have been better cast as Allee's son . . . From all appearances, it would have been easier to believe.
As mentioned in other reviews, the Grandparents appear to have come from "the old country", but can't quite figure out what to do with their accents. While never sounding Italian (as the names Gianna and Franco would suggest), they do occasionally sound Greek, Swedish and even Dutch.
Lastly, the villan in this pic is the female CEO for Wine, Inc. (no kidding) and seems to have come directly from Disney Central Casting. She's clearly studied Cruella de Vil for tips on how to play this part and it'd be laughable if it weren't quite so pathetic.
Having been filmed on location in Australia, there are several gorgeous scenes of the countryside. Unfortunately, that's not enough to save this movie and make it watchable. Hard pass on this one.
