Bad movie.
This movie is funny but only parts of it, I laughed then for a while did not laugh then laughed again then again did not laugh, this was for the entire movie. And also some parts are idiotic which often goes well with comedies but in this movie it was not idiocies that were funny (good example is the start - the part where she breaks his computer is too much - there are many more examples like that and some are even worst like when he takes the mom of 1 of his coworker that also suffers from alzheimer and then takes her to a small noisy awful house).
The script is very bad. The music is bad. The cinematography, special effects and story are average. The directing, editing, sounds, costumes and sets are good. The acting and makeup are great.
