It actually has three seasons, and they're all 12 episodes long. The characters become much more defined as you go on through the series. I hope you end up liking it more!
I normally don't like series like TGWOK, but I recommend you try watching more of it. It's actually pretty good. It starts out episodic, but it REALLY picks up, and becomes much more interesting with a large interconnected plot. You should give it a try if you ever have time and are bored.
