Sad but not unexpected, Netflix often kills shows after 3 seasons.

Its not entirely clear why but speculation is that they sign the stars on initial 3 year contracts, so renewing a show past that requires new contracts, which generally costs more, but doesnt bring in enough new customers to cover those extra costs. (Yes, I did read that the 3 year 'rule' is denied as the reason in this case, but I take that with a large dose of salt).
