I think it's kind of funny how the bbc series made Mycroft into a more authentic Sherlock.
I always got the feeling that Mycroft in this series feels like a more classic Sherlock aside from a few throwaway lines about not having enough interest to do legwork in cases and his government role. The classic victorian like outfit with the watch chain and walking stick, the mannerisms.
I think Benedict Cumberbatch could make a more likeable Sherlock if given a script that respects the source material more without wanting to subvert and invert it.
If there was a episode where they removed the few Mycroft characteristics in Mark Gatiss's Mycroft and added just a little more eccentricity to his portrayal i think he would play a great Sherlock.
I don't like the more mean, cold and many times pretentious reinterpretation of Cumberbatch Sherlock, but it's funny to see that right there in the same exact show there is a better, more classic option walking around as another character.
