The worst offenders for me in terms of achievements are the ones that require you to to restart the entire playthrough if you miss ONE thing, examples of this are the "Chatterbox" (Tomb Raider 2013) "All conversations with the Endurance crew completed.", as well as "Conversationalist" (Assassin's Creed) "Go through every dialog with Lucy.", these just suck.
As well as achievements related to going down specific choice paths, for example if there are two choices and there is an achievement tied to each choice, those are bad achievements. For example, just look at the achievement list for "Spec Ops: The Line", or imagine if there was an achievement tied to each ending in Mass Effect 3.
Also, games which have achievements such as "Collect X amount of Y", "Kill X amount of enemies", or "Do X, Y amount of times" MUST have a progress tracker, especially for collectibles so that I don't have to go back to one level or area looking for audio logs or dog tags or whatever.
