And of all the puzzles how was day 12 the only one I got wrong first time around?

#NetflixChristmas Reviews 2025 #2: Haul Out the Holly.
Single woman returns to parents' huge house for Xmas. HOA insists she decorates the street. Instead of leaving, she falls for HOA president. Painful. Talent wasted on the script. Clearly summer. Is it a spoof? Took me 3 days to watch.

A Hallmark Christmas film, but thankfully not one of the really cheap feeling ones. Has the other one from Mean Girls in it, who obviously goes to a small town to celebrate Christmas.

Idk why but this reminded me of Emily in Paris even though main girl is competent at her job. Maybe it's because of the scenes where French people talk to each other in French. Anyway I liked it, nice Christmassy escapism. 🇫🇷🍾🥂🌲🎄❄️/5

Workaholic American goes to Paris; gets involved in a champagne business; falls for a Frenchman. It’s Emily in Paris + tinsel. Starts weak but side characters improve over time and I actually laughed at points. A strong start.
