I'm beyond disappointed, I am LIVID.
I've been really disappointed with the show this season and the excessively gratuitous manner in which changes are made. I understand changes like Asha to Yara, and giving some characters more screentime who don't appear very much, BUT IF YOU DO THAT THE CHARACTER SHOULD HAVE SOME CONSISTENCY WITH THEIR CANON PERSONALITY. Tyrion's morally wrong actions are basically gone (bar Shae's murder), Jaime is now a rapist who despises rape, Cersei is by turns sympathetic, jaded, utterly insane, and not!Cersei, Arya is obsessed with killing because "it makes her feel good;" I could go on about this for hours. If this AU fanfiction of A Song of Ice and Fire is going to keep sucking, I won't be here for it.
Also, I read details of a casting call for Obara Sand that essentially said Jaime is going to Dorne. Goodbye Catelyn Stark, and fuck you D&D for turning a major character into a background prop.
