At the centre of the Mrs Doubtfire story is the desire of a father to bond and spend time with his children and the only means he knows how. It's about a family growing and experiencing life together. The end of the story shows how families can overcome adversity and be stronger at the end. To pursue a sequal would be to suggest that the ending was not as 'happy' as we all hoped it would be. It would identify frailties in family life which we don't want to see as we want the happy ever after ending.
I think the only reason they are remaking the movie is because of the name. The name of the movie is remembered by most people. Meaning, I think Hollywood movie makers are just trying to put out a sure thing to get max profits. To bad they kind of ruin a classic if they do not do it right.
More than often , sequels do not stand up to the expectations of the audiences. The film , Mrs. Doubtfire, ended on good note. People like the ending . Now stretching it further will be like spoiling the good memories of first film. The years have passed since first film and the actors have grown old. Casting new faces will not be acceptable.
While Mara Wilson is free to express her opinion on a sequel to the 1993 movie 'Mrs. Doubtfire' I don't agree with Ms. Wilson's assertion that there should not be a sequel to the film 'Mirs. Doubtfire.' Since the original director, Chris Columbus, and the original leading male, Robin Williams, are both signing board for the sequel others see value in the project as well.
