I honestly don't see what the problem is. House MD is essentially Sherlock Holmes as a modern American Doctor.
Sherlock Holmes is my favorite character...well ever. And I love the BBC series, heck I even like aspects of the RDJ films. The existence of this show doesn't really take away from any of those. We will always have the short stories, novels, and countless films.
I will give this a chance. If it's good, I keep watching. If it's bad, I ignore it. No harm, no foul. Trust me, if you research Holmes there are MUCH dumber concepts based around him.
