While your points seem valid to people who read the books but to the average GOT watcher, HBO is creating a series BASED off the novels and they're tweeking it to appeal to the masses.
My gripe with the show is that it very rarely rewards the viewer with the innate craving of seeing good triumph over evil.
For instance, Cersai is in prison, which is gratifying to me. However, I highly doubt HBO will pull an Eddard Stark and shockingly kill off a key antagonist to gain "shock value".
