I don't care for this version
I am a big fan of both Martin Clunes and "Goodbye, Mr. Chips" by Hinton. The book is rather short and leaves a lot of latitude for screenwriters. So there is no crime in interpreting the original story in original ways. However, I really did not care for this 2002 edition. It seems more intent on shoring up our current interpretations of what is good child rearing by having Chips mouth opinions from the year 2002 rather than something that would have occurred roughly at the time the story is set. I much prefer the 1939 version which was much more interesting and moving than this version. It showed Chips evolving over time into the beloved Master rather than this version which really doesn't have any character arc.
Maybe I should enter the Bad Hemingway Contest
