It is nteresting reading reviews of many films that get bad reviews. Frankly, it is ridiculous that someone may expect much from certain movies, get disappointed and place a negative review about what he or she experienced and not about the movie, really.
This is a Hollywood chic movie with a couple of known names. Plot, script, and premises are not something to talk about. It brings a couple of peals of laughter, nothing spectacular, but it is not indeed a comedy film. It is a little movie about a bit of something in a family of a mother and her three children — one who does not get dates because she doesn't know how to. Mother enters the field by using a dating service. Although it works, it complicates life between mother and daughter and the siblings... well, cover for their mother.
Performances are adequate for no real character development. This film was not made to awe anyone, including IMBD. Likely got some audience but was not a hit. That is what you can expect from this movie after you read the description, not more. I enjoyed it though.
