This piece gives this review from The Irish Times.
* IRISH TIMES

Thoughtful, powerful and moving Irish political drama, it is,
unsurprisingly, politically loaded. The Black and Tans are depicted as callous, belligerent oppressors, and there is, perhaps, one scene too many to emphasise their sadism.

The piece also has some fascinting memories from a Mr. Keating who fought against the Tans and in the Civil War. He says that his opponents in the Civil War were much worse than the Tans.
