I suppose the real question is "why bother remaking some films that still hold up as they were".
To appeal to the younger generation that doesnt watch older movies.
Most teens and early 20s people these days have never watched anything prior to 1990.
Hell, I'll be the first to admit its very rare for me to like any pre-70s movies, as I find them horribly dated (and yes, the 70s are dated, but I grew up with those movies).
