I'm seeing a lot of shows here that weren't particularly "acclaimed," just popular more than anything else, stuff like CATS and MAMMA MIA.
If we're talking about Highly Acclaimed, as in award-winning and well-reviewed, the most wildly over-rated things I can think of are DOUBT and that monument to Over-Hypedness: THE HISTORY BOYS, two of the most useless evenings I've ever spent in the theatre.
