Holmes and Watson will be back solving cases next season. CBS has renewed the Elementary TV show for a fourth season.

A contemporary update on the Sir Arthur Conan Doyle characters, Elementary follows eccentric detective Sherlock Holmes (Jonny Lee Miller) and Doctor Joan Watson (Lucy Liu) as they help solve crimes in New York. Aidan Quinn and Jon Michael Hill co-star.

The series has taken a big hit in the ratings this year. The third season is averaging a 1.29 rating in the 18-49 demographic with 7.44 million viewers. That’s down by 25% in the demo and down by 15% in total viewers.

Still, it seemed a certainty that Elementary would be renewed for a fourth year. The next season’s installments will give the crime drama enough episodes for a potentially lucrative syndication package.

What do you think? Do you like the Elementary TV show? Do you think the fourth season should be its last? Would you like to see any changes made to the show — to help attract better ratings?
