As a concept this film has all the makings of a hit and I suspect it could have been one with a higher production budget. There's not one element that is consistently bad, but nothing that is consistently good, either. The writing and acting are both good at various moments of the film, but there are more segments with unrealistic cheesy writing and also acting that makes Hallmark look professional.
However, the biggest distraction to viewers is the elements from post-production, mainly the addition of musical or tonal elements to nearly every scene as an attempt to stir the viewer emotionally. It was too intrusive, distracting and unnecessary in at least half the places where it's been added. The Field of Dreams esque whispers were just ridiculous, though.
The film has a worthy message and with some additional editing, could be worthy of a theatrical release. As it stands, I would wait to view it on streaming or other media to have control of the volume when the over the top background accompaniment can be turned down.
