This series is so spectacularly bad on almost - actually strike that - every level, it's almost worth watching just to soak up its sheer awfulness.
And I'm not just deliberately hating on it out of badness.
Simon Amstell - the real-life Simon Amstell - is a charismatic, likable, ferociously witty young man who manages to stay on the right side of smugness.
And Rebecca Front is one of my favourite comic actresses - glorious as a foil to Alan Partridge in the Knowing Me Knowing You days.
But, goodness, do they sink to the depths in Grandma's House.
I sometimes wonder during the process of making a show as execrable as this, why a friend or a colleague of the makers doesn't point out - politely - how bad it is.
Does no-one notice when they watch the rushes how painfully inept it is.
So what's so bad? Well, the acting for starters. For someone so effortlessly relaxed with pithy putdowns on Buzzcocks, Amstell is surprisingly uncomfortable in front of the cameras.
It's like watching a particularly stilted sixth former during am dram.
And, Jesus wept, the script. The second episode seems to have endless scenes of Amstell's character arguing with his aunt: "You shut up!"
"No, you shut up!"
"No you..."
That's not direct quotes but that's the gist of that 'plotline'.
It 'climaxes' in a scene where Amstell's mum and various family members act out a new play he has been working on about - sighs - talking eggs.
Can't bring myself to elaborate on that one.
In fact, I've whinged on enough about this.
Devoid of laughs, it's kind of worth catching in a cringeworthy sort of way.
