For films, I find that remakes are often unnecessary and not additive, to the point of sometimes being offensive or at the very least, off-putting.
But for video games, the technology changes so much that I feel a bit differently. Some of these classic games need to be played to be appreciated as cultural touchstones, but the graphics or controls are so outdated that they're essentially unplayable.
So, I'm a bit conflicted, but I guess I'm for it, so long as we're not just perpetually remaking the same crap over and over.
The Ocarina of Time remake trailer got me thinking about this, by the way.
