I've been a Sherlock Holmes' fan for what feels like forever, and, like others, was concerned that this modern version would be a disaster.

I needn't have worried. It was a terrific, fast-paced, edge-of-the-seat adventure. Benedict Cumberbatch (what a name!) brings a dark edginess to Holmes that gives the whole piece a delightful 'gothic' feel, while Martin Freeman - if the first episode is anything to go by - will make a perfect foil as Watson. Casting is so important and this combination feels just right.

I'll always have a soft spot for Basil Rathbone's Holmes, and, on the small screen at least, I can't see anyone displacing Jeremy Brett as the definitive 'Victorian' sleuth. But maybe, just maybe, the writers have created a Sherlock for the modern age who will stand the test of time and join a handful of other portrayals in the Pantheon of the greats.

Moffat's pedigree as a comedy writer has added a new layer to the Holmes' scenario, and though there were several in-jokes in the first episode that only Holmes' aficionados would appreciate, there was enough general humour to lighten what might otherwise have been a dark canvas.

Of course, I shouldn't have had any doubts. Steven Moffat is, after all, the man who rescued Dr Who from the self-indulgent, soap-opera obsessed, poorly scripted, moribund years of Russell T Davies and turned it back into a fun-packed joy to watch. He's done the same with 'Sherlock'.

The man is a genius. I can't wait for the next instalment.
