I discovered Peter Robinson's Insp. Banks a few years back and have read most of the books, best read chronologically.
In the main, I've not been disappointed.
The television adpatation was a shambles, unfortunately, and Tompkinson's portrayal one dimensional. More Wire in the Blood than Morse is how I would sum it up.
Am wondering though, if there are any plans for more as Annie Cabbot was welcomed into the fold by Banks so warmly!
I'd say read the books before judging the author.
