So, so far here the general feeling is the show's not perfect but okay, Herman could have been cast better, it probably wouldn't have made it as a series and Eddie Izzard - unsurprisingly - owned it. And there's one absolute 'No.' Sounds about right.
Personally, I think it could do well with one of those 6-episode deals. I doubt you could sustain what was in the pilot for 22 or 13 eps, but it shouldn't be that hard to make it work for five more shows.
