^^^Generic? Generic means no-name, just the general product. Sherlock Holmes is pretty much the name in mysteries. Also an Asian female Watson isn't a safe approach. What you're saying makes no sense. Either you are wrong or you are using buzzwords instead of saying what you really mean.
It makes a lot of sense. If you took away the name Holmes and Watson, this show would be a lot like a lot of other shows... the consulting detective (Castle, The Mentalist, The Show With The Guy From Will And Grace.)
It was a bland, safe hour of TV.
And personally, I thought there was zero chemistry between the two leads. How much chemistry can there be between a Brit and a piece of wood?
