Um, I've seen Les Mis over a hundred times so far! But I know folks who've seen the show 500 times plus.
Why? Well cos I love the show! Its live and therefore often never quite the same twice and with different casts adding new facets to a character. I love the music too. And there are characters within the show with whom I can identify, notably Eponine. Plus my favourite character and my favourite show tune is Javert and 'Stars'. I just adore listening to that sung with power (cue Michael McCarthy).
If I wasn't still in some way into the show or moved by it, then I wouldn't want to go and see it as often. In fact over the last couple of years I have seen the show less per year than previously just to ensure that I never get fed up with the show. So each time I visit the show I really enjoy the occasion

I have seen other shows several times, but 'only' in the 10s or 20s!!!
