I like remasters... When they're done well! The latest example is, of course, Crash Bandicoot. The entire game is intact, but it looks, works and plays so much better. And they're not selling it for full price (looking at you, Activision). It's $40,- for 3 games, which is a great deal nowadays.

With games like GTA V, DOTA 2 or League of Legends having continuous updates works well, but at some point they tend to get too big for their own good. Or it's trying to be relevant for so long, people will get bored of it.

All in all, I think remasters should be well thought out games that are improved replicas of the original. Not direct originals with some improved textures here and there.
