One thing you can definitely say about Lifetime is that their assigned movie titles are pretty handy for anyone who can't be bothered scrolling down the IMDB page to the synopsis - you can figure out what the movie is about thanks to the title.
"My Nanny Stole My Life" aka "She Wants My Baby" is no different. Crazy nanny moves in, tries to take baby and husband, wife must thwart plot. No spoiler here - it's all there in the title.
These made-for-TV productions usually about revenge and crazy or deranged people are good fun. They aren't great films, but they're entertaining in a strange way and when you get some decent acting, as there is in "My Nanny Stole My Life", you can get lost in the story. It's all implausible with plot holes big enough to drive an eighteen-wheeler through, but nonetheless they're oddly compelling
And sometimes there is a twist that you don't see coming.
