Remakes of older games

[VaeVictis]

After reading up about companies remaking Oddworld and creating a Legacy of Kain MMO, I found myself becoming rather cynical about originality in the gaming industry. Not that I feel a reactionary revulsion of a game being remade with modern graphics and such, I think it's best to at least give these things a try, but it seems that more often than out, all that's added are higher resolution graphics, some fan-service, and a few extra dynamic camera angled shots.
On the other hand, it's fun to see that the games haven't been entirely forgotten, and perhaps get a new audience to enjoy these games.

What do you think? In general, do you enjoy modern remakes, write them off, or do you maintain cautious optimism and give them a try?
