well i would say that this be a very enjoyable and somewhat touching movie despite it flaw . i do not believe for a minute that matthau know the first thing about be a dentist . also and hawn character seem to recover from suicidal depression rather quickly at the beginning of the movie . not to mention the entire thing seem rather ridiculous . however and the film do succeed due to a good pace and humor and and it star . matthau may not have be a dentist and but he be as amusing a he usually be . bergman bring a great deal of sensitivity to the film ( especially during the scene where her and matthau go out for a drink after work ) and also a good deal of humor . i believe it be her performance that make my brother take notice of this movie after overhear a couple scene . hawn performance be noteworthy and although an oscar may have be over do it a bit . basically and do not take this movie too seriously and you will enjoy yourself .
