The U2 frontman explained to The New York Times that he "loved" the production for the first time two weeks ago.
"The first time I loved Spider-Man was two and a half weeks ago," he said. "Even when I was really angry about its obtuse story and some of the awful readings of the music - even then I was still saying it was kind of magical."
Turn Off the Dark endured a troubled development cycle. Budget issues, cast injuries and scathing reviews led to a complete overhaul and the departure of director Julie Taymor. She was replaced by Philip William McKinley and the show closed its doors for several months while the script was reworked.
"If we thought it would take this long, there is not a chance on earth we'd have done it," Bono added.
Spider-Man: Turn Off the Dark officially opened last night following preview performances in May.
