I've seen him in a few things and he was just OK but holy cow as the villain in season 6 of Dexter (don't have to use Spoiler tags, I've spoiled most of the series as I'm watching for the first time). Reminds me of I don't remember the character but there's a boy with magical powers in that house for orphan boys was it Grindewald? Dark religious nuts I'm loving him in this.

I enjoyed his short lived TV series - The Good Guys - with Bradley Whitford

"Life in Pieces" was underappreciated. It should have gone a few more seasons.

He was great in the first season of Fargo.

I tried to find that great Dan Stark gif, but I was unsuccessful.

For a moment, these appreciation threads have me going oh no, so and so passed away, no way. But then I read through the thread and it is just folks pointing out many of the characters that Colin has played over years and that yes, he is a bit of an under-rated tv actor. I really enjoyed Life In Pieces. He also did that movie Orange County (with Jack Black) that was also a fun film to watch.
