I had waited to watch this movie because the ads made it seem like it was going to be tough to watch. All I could focus on when seeing the ads is how the female lead is so monotone and has such a flat delivery.
Having watched the movie, I will say that this is certainly a problem that detracts from the story, which is unfortunate because I love the idea of more realistically sized women being leading ladies. The national average is closer to a size 14 than a size 0, I think they should have no trouble finding an average-sized woman who can deliver lines more convincingly. I've only seen her in this movie, so it's hard for me to know whether she's not a good actor or if she just wasn't good in this part. Who knows, maybe it was because they put her in a jacket that was 2-3 sizes too small that she was self-conscious and struggled to be comfortable as the character.
Also, I understand that characters must grow towards each other to fall in love on these hallmark movies but they started out at such different places. In the beginning he so clearly did not respect her and she came off as detached and disinterested so it was hard to buy into them being potential love interests or them being in love at the end. As I was watching, by the end I felt they gave off 'friend vibes' not 'hopelessly in love vibes'.
It's unfortunate because I liked the idea - it was different than the run-of-the-mill hallmark Christmas movie with the usual checklist of plot points - but the execution didn't live up to its potential.
