I saw it and was disappointed; the movie justifiably spent time showing the husband's struggles (and failures) in his marriage and the effort he put back into wooing his wife.
However, the wife's own failures were, for the most part, ignored and there was no similar growth for her character (an older woman, a minor character, does try to express concern when she is seeing a young, handsome doctor while married, but the wife dismisses her concerns and shuts down the conversation.
The movie would have been better had they showed that BOTH parties need to work in a marriage.
Early in the movie and the book
FIREPROOF Catherine makes two decisions:
1) To divorce Caleb
2) To carry on a relationship with Dr. Keller behind Caleb's back.
Everything Catherine does is based on these two decisions until her "moment of truth" or "appointment with destiny." Even after Caleb's destruction of the computer and his appology she still plans to go ahead with the divorce. Only after Mrs. Evans straightens out her erronious belief that Dr. Keller paid the full price of the bed and power wheelchair for her mother does she change her mind. The book says she is "stunned" when she finds out it was Caleb who actually used his entire savings of $24,000 to pay for them. The movie clearly shows she is
stunned by the news. By the grace of God she never has an "affair" with Dr. Keller~!!!!!!!
