As long as the remakes add something to their own into the situations, I don't mind them. They might attract a new(er) audience, so I don't see a problem with that.

For example:
The original films were done over 20 years ago. There's plenty of individuals alive that weren't then, so you've got box office draw right there. There's also plenty of individuals (like myself) who weren't into the cheesy way the series was done back then, so, you run the chance of drawing those fans in. Then you have the new stars, their fans, etc, who will go and see it just for them. Then you've got the die hard fans who will see every movie in the series (again). This all amounts to good cash. Lucas proved this very well with the successful re-releases of the second trilogy into theater. I'm certainly not comparing all classics to the SW saga, but , the potential is most definitely there.
