The Fillmore's classic marquee has been replaced with a new giant 'F,' spawning criticism from some Detroiters who lamented the old sign.

Emblazoned with a blue swirling pattern, the new marquee consists of a tilted 'F' overlaid on a red, rectangular background.

It was met with dismay from some Facebook users on Monday, who expressed their love for the old sign on a picture that Detroit photographer ACRONYM shared.

"The old sign fit in with the block, this one is tacky and looks like it belongs in a strip mall," wrote Ryan Niederstadt.

"Sucks," added Benjamin Hayes simply.

The 'F' replaces a more traditional marquee sign in front of the venue, which reopened in October after four months of interior renovations. The upgrades included repainting the domed ceiling, installing intricate canvas murals and deep-cleaning the proscenium and marble columns.

The Fillmore could not immediately be reached for comment, but the Free Press reported in October that the logo would sport a digital board like the Fox Theatre's marquee next door, rather than letters workers have to change by hand.

Others, though, greeted the cherry-on-top more positively.

"Not sure about these negative comments, wondering if they had seen the old marquee," wrote Joe Orlando. "Can't wait to see the rest."
