The sad thing is that it is a truly great work of literature by the last great English novelist and it will be ruined in a two-hour movie.
Additionally, it was made into a multipart miniseries in Britain years ago, a series that was true to the book and with an unsurpassable cast.
Anyone who is truly into this sort of thing will have at least seen the miniseries when it ran several times on PBS or rented it on DVD.
The novel was about finding redemption in the key scene where Lord Marchmont (who lost his faith) accepts The Lord at the hour of his death.
