Yeah, I'll drop in on that. Original Holmes was a doped-up misandristic misanthrope who was eternally bored with the world and wanted a roommate to pay rent.
TV (modern) Sherlock is someone with bad social skills who solves problems with the power of being smart and occasionally friendship.
There is very little respect for the source material where Holmes is concerned. And that's fairly constant. The difference between Holmes and say... Ghostbusters is that people reacted heavily to Ghostbusters because it was a well-known movie. And that's on the viewers. If people actually read Dirk Gently and realized how full of wonder that series actually is they'd decry the TV show in a heartbeat as something that's pulled a bunch of things that are popular now, and used them to cover up something fantastic then. (probably more likely to make excuses for the show but the point is still there.)
