I don't mind when they don't follow the books.
Bran's journey to 3EC is very boring. Lots of trudging through snow for chapters on end.
In the books, he has no choice to go to the 3EC, but the detour on the show gives him the opportunity to make a decision. Go back with Jon or look for the 3EC and see if the legends are true and he can use his powers. It is the nature of converting the series to the show though. Season 1, for me, was probably my least favorite TV season.
Unless, of course, you guys want to see Brienne going on asking about a maid of ten and three for a whole season
