Yup that's pretty much how I feel also. Their death wasn't satisfying to me, it was more of a cop-out. I wanted to someone to look them both in the eye and stick a knife in them. If I look back throughout the seasons on it all, and all the times I felt how utterly hateful and for want of a better word "evil" Cersei is, and to know that at the end of it all, they would both die like this together, I would have been really deflated.
