Haven't seen it and now I'm in a bit of a quandary.
On the one hand 'Richard Curtis style rom-com' makes it something I'd avoid. Ditto Def Leppard being in it. Also, that some of the acting is poor.
On the other hand
Rory Kinnear is in it and he has been superb in every role I've seen him in so I'll probably give it a go.
The rest of the cast includes Paul Kaye, Cathy Tyson, Hugh Bonneville, Angus Wright and Jo Hartley, so a bit of a surprise some of the acting is poor.
