Mrs Brown’s Boys Christmas special review: I tried to like it but it’s still worse than cranberry sauce and Whamageddon

Over the past few years, a new Christmas ritual has entered my life. I find it easily the most irksome of them all, far outstripping cranberry sauce (I mean, what’s it even doing) and Whamageddon. I refer, of course, to the duty that falls to me to review Mrs Brown’s Boys, which never fails to disappointment me in its abject poverty of ambition.
