I played the original Myst ages ago and decided to replay it recently but I got stuck somewhere in the middle and stopped last week. I'll try to continue the following weekend but I will have to invest a lot of time to solve the puzzle and I'm not sure whether I manage it.
Anyway, I like the game and the idea of Myst. It's quite unique and the atmosphere of the game is magnificient. However, I can understand people who don't like the game. Myst requires lots of patience and you don't have any action to make it more attractive. It's probably the slowest game I've ever played (which is not a bad thing).
