From the New York Times:
"The show stopped five times, mostly to fix technical problems, and Act I ended prematurely, with Spider-Man stuck dangling 10 feet above audience members, while Act II was marred by a nasty catcall during one of the midperformance pauses. … Most of the night’s major flying sequences — which make up a relative fraction of the show — went off without a hitch, with children and some adults squealing in delight. And there were no signs of injuries, which had been a point of concern after two performers were hurt during an aerial sequence this fall. … After the show, several audience members said in interviews that they would hold off on recommending the show to friends until improvements were made. But Marc Tumminelli, 30, who runs a Manhattan acting school for children, said he was concerned that the musical’s problems were too fundamental to be corrected quickly. “The story-telling is really unclear and I found it hard to understand exactly what was going on and why certain things were happening,” Mr. Tumminelli said. More delighted was the 6-year-old boy sitting a row ahead. “Parts of it were really exciting,” said the boy, Jack Soldano, whose parents brought him. “I’ve never seen people flying before.”"Read the other criticisms collected on /Film.
