I think it's a very sweet film.
Another Disney film from the 1990s that I and other reviewers evidently disagree on; an average rating of 2.2 on Letterboxd is very harsh, in my opinion. I found it charming and suitably acted.
I assume the major dislike of this film is the secondary plot featuring Joey (Richard Portnow) & Co., which I would agree is unimaginative and ill-fitting. However, that doesn't affect my overall feelings. Another thing I see mentioned is the Native American stuff, I don't think it's fair to say it's "racist" - insensitive? potentially - if anything, it mentions a few times the negative depictions; somewhat surprisingly, for a 1995 release anyway.
The story between Ben (Jonathan Taylor Thomas), Jack (Chevy Chase) and Sandy (Farrah Fawcett) is nice. It's simple, but it's one that works extremely well - I felt attached to them, they have good chemistry with each other.
There's not much more to be said. I truly did enjoy 'Man of the House'.
