I have not read the books, but I did see part??? or maybe I waited out the whole movie??? And if the book is ANYthing like the movie, I would say that these are NOT something I would want my children observing. The theme of the movie was just SO dark. There are so many wholesome alternatives where the heroes may encounter hardship, but not on such a perpetual, unrealistic, catastophic basis. If you do a search for book recoomendations for boys on the forum, you’ll find lots of great suggestions.
We measure EVERY book, movie, song, etc. against Philippians 4:8.
“Finally, brothers, whatever is true, whatever is honorable, whatever is just, whatever is pure, whatever is lovely, whatever is commendable, if there is any excellence, if there is anything worthy of praise, think about these things.”
If it doesn’t pass that “test” then we don’t use the material.
