Some will cry “Sacrilege!” but I watched the 1974 and the 2009 versions of this story back to back (almost) and found I like the 2009 version better. I had fond memories of 1974, but a rewatch reveals a pretty flat procedural. 2009 isn’t great by any means, but I found it more engaging – I cared a little more about the characters and what was happening. That said, I don’t see much purpose in remaking the film (or most other remakes, for that matter).
