Could have been great, but fell short.
Saw a preview for this flick and thought, 'damn, there's a good movie premise, and the actors are all excellent". when i rented it, however, i was sadly disappointed. One of the really obvious downfalls for this movie is the soundtrack. the dialogue gets a bit cheesy here and there, but it would have been acceptable were it not for the Hallmark signature piano track behind it all. this movie isn't supposed to be a tear-jerker, its supposed to be informative, funny, and gripping, all of which would have been much more effectively transposed with a much less active score.
Overall, this movie was alright. it should definitely not be compared to Sideways because these are two completely different ideas. So they are both about wine. That would be like comparing 'Speed' and "the darjeeling limited" because the drama in both takes place on a moving vehicle.
If, you haven't seen this movie yet, Go see it. its worth watching once. it tells an interesting true story and makes you want a glass of wine.
