Well - it's being sung in the original French - it's not clear from the website whether or not there will be 'surtitles' to translate.
Personally, I always think its better when the opera is sung in the language it was written for (i.e. not in English). I saw another production of this years ago and enjoyed it, but am not sure if it's a good one for a first opera experience. My recommendation is always for 'La Boheme' or maybe one of the Mozart ones - it's very much an acquired (and addictive) taste.
But, having said that - we don't have a huge choice in Dublin, so why not give it a try ?
