Rastakhan had more flaws to him and it's a shame he never got the chance to go back to being the strong king we're told he was before he got complacent and that he accepts again leading up to the final showdown with Zul. Talanji has grown on me over time, and the scene of his death with the two and Bwonsamdi was everything I'd have liked, but she still has a ways to go.
On the plus side, the door is open for him to make further appearances, since he's sworn to Bwonsamdi in death as well as life.
