Next Paycheck:p

I have the complete first and second season, next month I will order Season three through Movies Unlimited. I have there 800 page catalog full of movies and tv shows.

Season 3 is the best. I have it and I love it!

I just purchased myself the complete series, having only seen selected episodes on You tube.

I am now on season 2. The show is a bit meh in season 1. It was very much a show that needed time to grow.
