Mother-in-law, played by Jane Fonda, does not approve of her son's girlfriend, played by Jennifer Lopez, and sets out to make her life as miserable as possible. What ensues is hilarious drama, with a valuable lesson at the end. I have watched this movie several times.

Jane Fonda was fantastic as Monster In Law! I enjoyed this storyline so much, a lot of really great laughs. Felt so bad for Jennifer Lopez, she played such a great character too. Have watched this movie several times.

Jane Fonda was hillarious in this one and I loved it. I had never known her to act in a comedy role before something quite unexpected and she came across wonderfully as the great actress that she is.

Oh my god, I loved this movie. Jennifer Lopez and Jane Fonda were fantastic in this movie. Jennifer plays the daughter-in-law to be and Jane plays the disapproved mother-in-law. This has comedy, romance and very entertaining.

This Movie is an all time comedy favourite in our house. My grand daughter and I laugh really out loud. Jennifer Lopez and Jane Fonda are funny. I love how Karma plays a part in this movie. I give this movie a 10 out of 10 rating for its humour , special features and it's hysterical scheming.

I've watched this a few times. Jane Fonda, Jennifer Lopez and Wanda Sykes. A hilarious movie when the son meets the girl of his dreams and the pranks that the mother pulls because she is so jealous. Worth watching.
