A bit of grief for Mike Leigh's 'Grief' at the NT

Hmmm... interesting. Some 'mixed' reviews for Mike Leigh's new play, Grief, at the National Theatre. I've booked to see it next month with one of my friends, Andrew, and am looking forward to it, despite some of the less enthusiastic notices. I am always bemused that Leigh's plays sell out at the NT, even when people don't know the title of the play, its theme or the cast which, in this case, includes the wonderful Lesley Manville (pictured).
