Worth a watch.
Have read many of the 4-5 star, as well as the 1-2 star reviews.
What drives this series is the acting and photography.
Does Alex do stupid things? Most definitely, the first being to leave at night, when she could just take off while Sean was at work; I am guessing the director wanted that scene to illustrate a mindset of desperation, especially when you suddenly see Sean standing there begore Alex speeds off.
She could have filed a police report; she could have gotten a waitress job, take up her father's offer, to name a few of the coulda, woulda shoulda, that everyone says in their reviews.
If the character did all those things, it would be as if they solved the zombie problem in Walking Dead during the pilot episode - there would be no series, no sympathy for the character and her struggles - or their struggles, since there are a lot of personal threads in this series.
Does it require, as Senator Clinton would say that we should "suspend our disbelief" to watch some of these things - mort definitely, but all shows are escapes of a kind, and very few use raw situations and emotion to get the real message across.
Is it worth watching, yes; does it address several societal issues, also yes; would it be completely accurate? probably not, but if it draws attention to the main subject, and gets people talking, or even acting, then it has accomplished something.
In Everybody Loves Raymond, Ray's mother makes a sculpture that accomplishes exactly what art should do - makes you think, and opens a conversation - in that The Maid is very successful - it has started people thinking about what constitutes abuse, and has US talking about it.
