This has been so very interesting. I devoured the books, and there have been a lot of things that are different, and with this season, some things that were left up in the air in the books were answered.....
The most interesting thing was that the author was working with the screenplay, so what so many fans would feel is "canon" is not...
Like Tyrion was on his way to meet Dany in the books, but met her in the series. This was soooo exciting to me.
There are a lot of deviations from the books, and I do understand about the change from one media to the other (the books were getting so complicated with characters and side stories)
But Jon Snow?
There are a lot of theories about this that I have read. Some theories have suggested that the Red Witch, realizing that Stannis is not the "savior" has returned to Castle Black in time because she has already resurrected someone and will do the same with Jon Snow.
Some theories have said that Jon Snow has a relationship with his Direwolf like Bran, and will be able to transport his "spirit" to it and still live......
Some theories have even gone so far as to suggest that Jon Snow was not Ned Starks's biological son, but perhaps a Targareon (sp?) and was protected.....
Jon Snow's character was built up as very important this season...not only was he elected head of Castle Black.., but the White Walkers seemed to be impressed with him. He holds the Valyrian Steel Sword that was able to kill white walkers in addition to the obsidian glass.,
This season was brutal. Very brutal. Stannis' decision to sacrifice his daughter was especially hard to watch. Although Cersei is such a bitch, it was still hard to watch her "walk of shame". (Ironically, as an SI member I kept thinking "the Karma bus has arrived"! but still....)
For me, the most interesting thing about the books and the series, is that no character is black and white good or bad. There is a lot of good in "evil" characters, and bad in good characters.
It's realistic in that way.
We all have our favorites.
I know, that many people really love Jon Snow, as do I. He is not perfect, but is a hero who has the best intentions, as did Ned Stark.
I LOVE Tyrion. Good and bad there
I LOVE Dany, she is so idealistic, but not perfect.
Perhaps we get upset because like real life, things happen in this series (and the books) that is not fair..
and that is what keeps us hooked.
