Charlie Sheen, currently on his 20-city My Violent Torpedo of Truth/Defeat Is Not an Option tour, received a scattered standing ovation at the Chicago Theatre on Sunday night, after bombing the night before in Detriot.

The former Two and a Half Men star, 45, made some bold changes to the format of the program after disappointed fans left the Detroit show calling for refunds, leading the the media to speculate how much longer the tour would continue.

By Sunday, Sheen had eliminated a rapper who was his opening act, his stream-of-consciousness ramblings, and various pre-taped video highlights of his career in lieu of a talk show format in which the actor discussed the "odyssey" that is his life, both personally and professionally.

A modest Sheen dubbed his Chicago show "the most epic night in Chicago f**king history."

"It was a canny shift of the show's tone, from epic self-aggrandizement to a more casual, at times even likable, persona," the Chicago Tribune's Steve Johnson wrote.

Sheen addressed his Detroit debacle during Sunday's show, reading a letter he wrote to the Windy City citizens.

He said, “Dear f **king  awesome Chicago. I am a veteran of a disturbing odyssey that had me question the very nature of my soul... I am speaking, of course, about last night in Detroit.”

Johnson wrote that "the Chicago crowd was ready to please him, too, delivering an unbidden 'Detroit Sucks' chant right away."
