This story contains spoilers for the Season 1 finale of "Fringe."

Entertainment Weekly's Michael Ausiello called it "ballsy." Other fans expressed shock.

Anna Torv's character of Olivia Dunham finally gets to meet the mysterious William Bell in the season finale of Fox's "Fringe" Tuesday, only to find out that it's not only Leonard Nimoy, but that he's working out of the World Trade Center in New York City.

Granted, it's a New York City in an alternate universe. But with Sept. 11 terrorist attacks just eight years old, could it have been a little too soon for the viewing public to see the towers used in such a dramatic way?

We turned to Twitter, probably the best place to find instant reaction, to find out.

"That was a bold image for 'Fringe' to end on," said @ambienceofmedia. "Countdown to some demographic becoming incensed over it."

It's not clear if a specific demo was angry with the Twin Towers or not, but there were some fans in the Twitterscape that didn't like what they saw.

"Not sure how I feel about the WTC in the end of the show," said @scottiewithers. "Seems a little inappropriate. Understand the shock factor, but wrong."

@jonathanblair was thinking along the same lines. "WTC in the end shot of 'Fringe'? Hope that didn't offend any relatives of loved ones."

"Seeing the Twin Towers on [tonight's] 'Fringe' topped the creepy scale," said @sushuma.

"J.J. Abrams, enough with the 'Star Trek' plug in 'Fringe,'" said @mmmaiko. "But nice 9/11 denial."

However, there were many fans who felt the inclusion of the World Trade Center was a nice twist to the show. And let's not forget, "Fringe" wasn't the first show, even this season, to use the towers. The premiere of ABC's short-lived "Life On Mars" also featured the towers under construction after its lead character ends up in the 1970s.

"Caught the last few minutes of 'Fringe,'" said @charlesjurries. "The closing shot? Creepy, in such an unusual, creative and unsettling way."

"The finale to 'Fringe' was epic," said @nateb2. "Wow, wow, wow."

"I will give you props 'Fringe' writers for having the balls to end the season with that shot," @robschmit said.

"Leonard Nimoy? World Trade Center? WTF?" said @z4mp1. "'Fringe' is enterting the realm of strange and sci-fi like 'Lost,' but I love it."

"Good on Abrams, [Alex Kurtzman and Roberto Orci] for putting that last shot in the finale of 'Fringe,'" said @matthamand. "Even 'Spider-Man' didn't have the guts to go there."

And we give the last word to @alaxthepixie.

"To everyone upset with the WTC at the end of 'Fringe,' would it be better to pretend the WTC never existed?"
