GameBanshee has reviewed Neverwinter Nights: Kingmaker and rated it 8 out of 10. Here's an excerpt:

All of the above is basically a prelude. The module itself starts when you finally reach the inside of the Keep of Cyan. There you'll learn that the lord of the keep disappeared some time ago, and that the people of the keep are finally ready to elect a new one. However, the nine guildmasters who decide the election are conflicted. Three want the evil and oily Sir Becket, three want the good but unyielding Enivid Divine, and three are undecided. Then, quicker than you can say “Why isn't the module named Lordmaker?” you're nominated for the election as well, and the bulk of the module involves you trying to convince the guildmasters to vote for you.

Collecting votes is a varied process. Some guildmasters will send you on quests to kill things, some will be susceptible to bribery or blackmail, and one will even offer to vote for you the first time you speak with her. What's nice (mostly) about the module is that you don't get to choose the time of the election. Every so often somebody will tell you that the election is about to start, and while you can do a quest that allows you to delay the proceedings a couple times, eventually you'll have to go through with it, whether you want to or not. That means you won't be able to complete all of the guildmaster quests with one character; you'll have to play at least a couple times to see them all. The bad aspect of this system is that you might feel hurried when you play the module, and you might be thrust into doing something before you've collected your bearings -- or even any equipment.
