The news that Ben Affleck will play DC Comics hero Batman in an upcoming live-action film has sparked a palpable outcry from observers, both fans and professionals alike.

Along with petitions calling for Affleck's removal -- one is currently at more than 15,000 signatures -- it's been a steady topic of discussion on Twitter since the announcement Thursday evening, with The Hollywood Reporter stating that 71 percent of the tweets on the subject in the first hour following the announcement were negative on the casting choice.

Yet the reaction isn't all bad, with comic book industry professionals like "Kick-Ass" creator Mark Millar expressing excitement over the news:

Ben Affleck will be a BRILLIANT Batman. Such a nice, intelligent actor. The backlash to his backlash is now complete. Love it!- Mark Millar (@mrmarkmillar) August 23, 2013

Image founder and recent DC Comics artist and writer Rob Liefeld was similarly positive:

FTR I dig Affleck as Batman. He will be .....RAD- robertliefeld (@robertliefeld) August 23, 2013

Scott Snyder, the writer of DC's current "Batman" series, explained to a fan in a four-part tweet that he's taking something of a wait-and-see approach:

@iMackyy honestly - embarrassing to admit - but the only time I was on board with the casting of a batman movie from go was Clooney...- Scott Snyder (@Ssnyder1835) August 23, 2013

@iMackyy ...& much as I like him in general, BF was my least favorite Batman film ever. I admit I was child of full on 80's Keaton fanrage...- Scott Snyder (@Ssnyder1835) August 23, 2013

@iMackyy ...then a Bale skeptic, even Ledger doubter - until I saw each film and ended up loving the casting. So truthfully...- Scott Snyder (@Ssnyder1835) August 23, 2013

@iMackyy ...I'm up for anyone I didn't see coming. And Affleck is a very smart, talented guy with good intentions - so I'm honestly game.- Scott Snyder (@Ssnyder1835) August 23, 2013

"Batman '66" writer Jeff Parker suggested historical perspective was in order:

Not defending, but everyone's saying the same things about Affleck that was said about Keaton and that one was cheered on opening.- Jeff Parker (@jeffparker) August 23, 2013

Marvel mainstay Brian Michael Bendis offered that there might be a pragmatic reason for Affleck's decision to take on the iconic role:

For those wondering why Ben Affleck would agree to be in this movie, I have the answer. my 10-year-old just asked: who's Ben Affleck?- BRIAN MICHAEL BENDIS (@BRIANMBENDIS) August 23, 2013

Beyond comic book industry professionals, opinions came from everyone including politicians:

Sorry I'm pro-Ben RT @tylerkingkade if elected, will you stop Ben Affleck from playing Batman?- Cory Booker (@CoryBooker) August 23, 2013

Comedians:

WOW, @BenAffleck is gonna play Batman. I hope he fights the Joke-ah! #wickedpissah- Patton Oswalt (@pattonoswalt) August 23, 2013
