This came out today, although I saw it a couple of weeks ago with Pamela Anderson doing a Q&A (and she is unreasonably gorgeous, as expected).
It's slight (possibly because it's 85 minutes and we've had weeks and months of sitting through 2hr+ films), but I really enjoyed it; Jamie Lee Curtis is fantastic and the relationships between all the women including her estranged daughter (played by Billie Lourd who is Carrie Fisher's daughter) are lovely.
Las Vegas looks faded and shabby but in a wistful, gentle way; apparently some of the showgirl costumes are vintage ones that had been worn on stage there years ago. I'll likely see it again once the Oscar stuff has calmed down
