The story, pacing and video side of the production including the acting were very good. However, the overall experience is let down by some rather shoddy sound engineering. Within the first 10 minutes, it should have been obvious to the Director that there was a shortfall. Considering the fact that I grew up in in Dublin and that I had to have sub titles switched on should be indication enough that there was something not so effectively done.
As stated in another review, the sound separation was abysmal for a modern production, even Smart TVs with Dialogue Enhancers and various surround enhancing alternatives did not do enough to help.
The Dublin dialect can be difficult to understand as certain words roll into others so it IS important. The speech coach should have realised this on first review as well and questioned whether it was actors' failings or inadequate sound capture and/or separation.
Interestingly enough, the actor that stands out as being the most articulate is the one who worked on Downton Abbey. Possibly the bigger a production is may demand more resources thrown at actor articulation?
Otherwise, as I said, I found the story very intetesting.
