Definitely don't read it if you actually plan to like any of the characters. Anyone you actually like will either be killed or ignored for several books. The plot is fairly obvious if you think about it, but it's largely ignored.
Almost all of the books are from the point of view of characters you don't care about, and the 'believably evil' characters are mostly annoying, especially when entire chunks of the book are dedicated to them, and then they somehow magically redeem themselves.
However, if you do care about what kind of dresses Sansa is wearing, or how her last cup of tea was, there's plenty of that.
