Disappointing news, but Lee Mack clearly has confidence that the show can go on - change is not necessarily a bad thing. I'm more than willing to give the next two series a chance.
Worth considering that tonight's episode is not necessarily Vine's last, as if Lee Mack has known about it for a while there could be one or two episodes as a handover period. I expect Lee would find a reason to keep Daisy in - Katy Wix is too good to lose even with Tim going.
It'll be interesting to see who they cast as a replacement. I'd like to throw Chris Ramsey, Sean Lock, Darren Boyd, Steve Edge and Jim Howick into a list of potential replacements, all of whom I think would have chemistry with Lee whilst not simply being a clone of the Lee/Tim dynamic.
