Mr. Mercedes Season Two:

[HumphreyBear]

That's good news. We (wife and I) have really enjoyed the first 9 eps of season 1.
I too thought the book series deteriorated. FK was ok, but EOW was just silly. I'm prepared to suspend my disbelief as much as anyone, but EOW was hard to swallow.
It will be good to see Brady again though. Harry Treadaway's characterisation is very, very good, and of course, Brendan Gleeson is wonderful.
Dennis Lehane on the writing team is a plus, on the whole, I think it's a quality production. And as I understand it, it's made by a phone company.

The biggest problem with the series for me is the travesty of plastic surgery on Mary Louise Parker. Her face looks ridiculous! Like nothing found in nature. I always enjoyed her performances but it's hard to get past that philtrum.

Good news. Though I thought that the trilogy deteriorated with each successive book!
For me, the 1st season has improved upon the original novel. Hopefully they'll do the same with future seasons.

Mr. Mercedes has been renewed for a second season.
