[S7E5] Thoughts on Danny

Not to defend Danaerys but I don't think she's gonna be a mad queen just because she kept her promise (bend the knee or die) she needed to do that awful thing of sentencing the Tarlys to death because if not, she would look like a weak queen next to Cersei and to the people in Westeros. On the other hand I don't think she's mature, wise and patient enough to rule but.. she had a point in taking care of the business herself. I don't think, as I mention before, that she could be a very good queen (she's kind of spoiled by everyone and also not the most humble person right?) what are your thoughts on this?
