Best thing might be the view outside the cabin. Script needed moments in which the leads would seem to connect more. They could've cooked dinner together or read a bit of that Dickens classic to each other. Needed other characters there more often, too, to create a broader world. Look up the preview of Write before Christmas, an actual Hallmark piece. Same lead actor. Ultra-predictable looking, but more chemistry and detail (setting, props, actors, extras) in that 30 seconds than in the entire Cabin movie.
