From John Doyle of the Globe and Mail:

• Bay Street banality
  “Billable Hours is not to everybody’s taste. That’s for sure. I find it crassly unfunny. It indulges in a kind of shallow, cruel comedy that’s all smirk and smiley-face and stunningly grotesque. This is the humour of sadism.”

From Lee-Anne Goodman of the Canadian Press:

• New executive producer brings edgier element to Showcase hit Billable Hours
  “All in all, it’s “Seinfeld,” “Curb Your Enthusiasm” territory – a long overdue direction for Canadian television, [Frank] van Keeken says. He points to another Showcase show, “Trailer Park Boys,” as a pioneer on that front.”
