I watched the entire first series in one sitting once at a friends house, during a drinking session after the fun had died down.
It was OK, and I usually like Danny Mcbride so it got extra points.
Didn't seem like it had enough going for it though, it was a 6/10. Not bad, but no belly-laughs.
Will Farrel seemed a bit out of place too, didn't fit in with the shows tone.
Never saw any episode twice, or any subsequent series, so I dunno what I'd think nowadays if i saw it again while sober.
