Hmm, I went to see it and thought it was ok, no better than that. It seemed dated and it is quite lengthy for a play (2hr 40) although that was before press night so it may have sped up a bit since then! Rob Brydon was good, although quite like his Uncle Bryn character from Gavin and Stacey so not a huge stretch for him there. I found the first act too long, beginning of the second act was far funnier and then it tailed off again. I wouldn't say don't go at all, but definitely get an offer on the tix!
Has anyone been to see the production currently on at the Harold Pinter theatre in London? My friend is there this evening and text in the interval to say it was hilarious. I really like the show and am planning to get tickets I think.
