3 to keep 2 to cut

-One of the most important scenes in the first book that absolutely would have to be kept is the scene where the starks discover the direwolfs. This scene obviously has a lot of plot importance but also includes a significant amount of foreshadowing.
 -Another scene that I love from the first book is the scene between tryion and John snow on their way to the wall. Tyrion has a pretty great quote in this scene because they are both outcasts that has to be kept in any film adaptation.
-Finally one part that i have a beef with in the second season (which i have already seen and read) is that they leave it 5 characters that stay behind in winterfell that help bran with his struggles significantly and that i feel absolutely should have been included in the show.

--Janos slynt from books one and two is probably a character with a side plot that isnt all that important.
--Now in the third book there are three men who have captured arya and are taking her back to their King but their part in her overall escape and story arent all that relevant and may just take up time unnecesarily.
