For me, I feel like after Nick left, the show got so much funnier. I thought Jon Ritchie got so comfortable as Artie's sidekick, the twins and Mike as comedic material. I miss this show.
I think DirectTV would have definitely kept it going past the 3rd year, if not for Arties addiction relapse potential/issues. It was a great show. Also, on that point - it IS Arties personality ( warts and all ) that made the show great to begin with.
Yea, it sucks man. These two really ARE good friends but they had clashing styles in the sense that Nick was willing to do what was required of DirecTV, while Artie was still struggling with his addictions. The reality is that they are both gritty comics who really complement each other, but professionally are at different places.
I'm pretty sure Direct TV was simply losing money and I doubt this show was bringing in a ton of viewers. It had more of a small cult following. At least not big enough for that studio and staff.
