I like them when they are done well. Achievements can encourage a new play through of a game I already beat and would have put down. Additionally, well set up achievements can encourage me to play a game a different way, e.g. Bioshock had one for getting all the tonics, which limited the amount of plasmids I could use because I needed to spend all of my Adam on tonics. My first time through I was playing heavily with plasmids, so the shift in focus gave me a new way to play a game I already loved playing through.
But achievements can have problems too. I hate multiplayer achievements for games with a strong single player focus (see also, I'm never 100% Bioshock 2). I hate achievements that look for difficulty but don't count downward, so beating the game on hard mode only gets me the hard mode achievement but not the one for normal and easy mode. And I hate starting up a game and hating it and having the total lack of achievements in that game tied to my gamer card for eternity. I know I hated X, but it looks like I failed at gaming. Also, I hate that DLC achievements get added automatically whether or not you have the DLc. You have all 1000 points that X game has to offer, but because you never bought the DLC, it is not actually completed.
And while I'm already talking about achievements, can we please stop playing up ME1's achievement layout. It required a minimum of 3 playthroughs to 100% , all requiring in depth play of the game not just speeding through the plot and invalidated playing 3 of the classes. The reward system was a nice idea, but that system was flawed to hell.
