Normally if I write a review it's for shows I really enjoy, posted only in a discord of mine, and a lot better written. But because this rare drama has no review, I shall write a very basic one. ( so sorry in advance if it's not up to this website's par haha).

First I'll just say I basically lost interest at ep6, half watched half used my phone (like to write this) afterwards. The story was obviously heading nowhere and none of the main characters showed much change, and I was right, like Shintani just ended up messing around with that woman who he said would make his, Noriko suddenly became attracted to Kisa whom she was completely uninterested in an ep prior, and Aya continued to mess with that married man despite knowing it's a depressing matter, etc.
Also I felt that most of the characters were two dimensional , especially the more side ones like Nagahori but also ones like Kisa and Kana, their characters were too predictable and 'scripted' if that makes sense. Then the Kisa family was straight up one dimensional, they literally existed to be a plot device this entire show.
I have other grievances with this show but they're all too small to speak about individually so to summarise them: every side plot was just added in an effort to bring more depth to the show but all ended up just being random side events.

Being honest, the only reason I finished this and got a 7 is because of Yamaguchi's (Noriko) performance, me having a significant interest in 80-90s entertainment (music included), the occasional comedic scenes, and the fact that I downloaded it (would be a waste otherwise haha). I'll probably end up rewatching this in the future and when I do I'll be sure to rewrite this or at the very least edit this to say my opinion has remained unchanged.

Also this is a nitpick but why is it called My 29th Christmas when it hardly mentions or shows it until the final few minutes
(シ_ _)シ (not counting the music)
