After 506 performances and four Tony Awards, Broadway's Hedwig and the Angry Inch will close on September 13, producers announced.

Taye Diggs is currently wearing the Farrah Fawcett wig and high heels, following in the footsteps of Neil Patrick Harris, Andrew Rannells, Michael C. Hall, Darren Criss and John Cameron Mitchell, who created the musical and orginated the role off-Broadway in 1998.

Not even the biggest Broadway smash lasts forever, but critics haven't been kind of Diggs.

On Monday, the New York Post's Elizabeth Vincentelli wrote that the Rent star was "complete miscast" as the East German trans rock singer.

"It has nothing to do with him being black and everything to do with him looking pretty damn uncomfortable in the role," she writes. "Diggs never connects with Hedwig."

Whereas good rock — not to mention good acting — flows from the gut, you never forget Diggs is performing, from his awkward strut in platform shoes to the pseudo-antagonistic audience interactions. How can spitting water onto the first row look so forced?

Even the cathartic show closer, “Midnight Radio,” falls flat.

Diggs seemed fairly elated when he took the part, telling the New York Times playing Hedwig was "everything I've ever wished for."

This is me telling myself, 'Okay....put your money where your mouth is. You've been telling agents and your best friends – I told Idina [Menzel] – 'I want a chance to show everybody everything. I can dance and I can sing, and everybody knows I can act.

Hedwig's brisk box office has also been flagging since Diggs joined the show on July 22: Last week, the show grossed just over $400,000, playing to 75% capacity—a decline from the average box office even after Tony winner Harris departed.
