Another Remake? Why?

Recycled from an e-mail to a friend, since I haven't posted anything lately:

You may have seen that they've remade The Day The Earth Stood Still, with Keanu Reeves as the alien Klaatu, and it opens Friday. This time, though, Klaatu's message is supposedly different: Instead of the anti-Cold War message of the original movie, this time he's going to tell us to stop destroying the planet. For some reason, I expect that he's going to get all Goracle-y on us: TDTESS meets An Inconvenient Truth. Feh! I usually dislike remakes on general principle. To me, it shows a lack of creativity and originality to just re-do something that someone has already done decades earlier. If it was good before, watch the original. If it wasn't good before, why remake something that sucked?

And no, I didn't think that the Will Smith version of I Am Legend was better than Charlton Heston's The Omega Man.
