It is interesting to read the rather divergent reviews of this TV movie here. Personally, I loved it, having been a long-time fan of all of the ladies. Not nearly enough of Liz in the film, sure, but Debbie has some great wisecracks and Joan not only looks amazing (hardly surprising she just married someone her son's age), but displays a genuine talent for comedy.
If anything, I was disappointed with Shirley's storyline and the unnecessary "gay son" aspect. Also, aside from the headliners, some key supporting players are sadly lacklustre.
However, it is what it is - sort of an updated "Golden Girls" set in Hollywood rather than Miami.
