This is another one of those stupid posts that I do not know why I respond to.
No, it is not.
I have seen the show 5 times, in 4 different productions, and I consider myself a moderate fan of the show, although every single time I have gotten bored at some point in the first act. Interestingly, although I hated Act 2 in the original production, I have preferred in in the subsequent performances that I have seen, most recently this summer in Boston.
There is one thing that I have to acknowledge: I can not think of another acclaimed show that has bored as many of my friends as this show. These are generally well-educated people who go to the theatre fairly regularly, if not as often as I do. At the Boston production, I went with 5 other people. Not one liked it, although all thought that Sunday and Move On would stay with them for a long time. This is the same reaction that I have heard from fellow viewers every time I have seen this.
I do think this is a show with more specialized appeal. It may be the best musical ever to a small group of people, but I doubt that too many people are going to consider it one. For myself, I think it is too slow at times, more than a few of the songs seem like filler to me, and it can be a little 'twee' here and there. I am forgetting the name of there song right this minute, but I personally squirm every time I see the number in which George imitates the dog he is painting. It is, to me, cringe-worthy, although I am sure there are others who consider it the height of brilliance.
