Jim Carrey withdraws support of his movie Kick Ass 2

The recent violent incidences that have plagued the U.S. recently have had an impact on American actor Jim Carrey.  A week ago, Carrey tweeted:

"I did Kickass a month b4 Sandy Hook and now in all good conscience I cannot support that level of violence.  (M)y apologies to others involve(d) with the film."

Kick-Ass 2 is the follow-up film to the Mark Millar graphic novel also adapted to film in 2010.  Like the graphic novel, the movie is a what-if vigilante scenario that centers around two teens (aka Kick-Ass and Hit Girl) who decide to take justice into their own hands and fight crime.  Unlike other movies that feature vigilante justice, the Kick-Ass franchise does not shy away from blood, profanity, or excessive violence.

In response to Jim Carrey's comments, Mark Millar wrote on his website:

"As you may know, Jim is a passionate advocate of gun-control, and I respect both his politics and his opinion, but I'm baffled by this sudden announcement as nothing seen in this picture wasn't in the screenplay eighteen months ago," Millar writes. "Yes, the body count is very high, but a movie called 'Kick-Ass 2' really has to do what it says on the tin. A sequel to the picture that gave us HIT-GIRL was always going to have some blood on the floor and this should have been no shock to a guy who enjoyed the first movie so much...Like Jim, I'm horrified by real life violence (even though I'm Scottish) ... This is fiction," he continues. "Kick-Ass avoids the usual bloodless body count of most big summer pictures and focuses instead of the CONSEQUENCES of violence, whether it's the ramifications for friends and family or, as we saw in the first movie, Kick-Ass spending six months in hospital after his first street altercation."

Although I respect Jim Carrey's opinions and sentiments, I tend to agree with Mark Millar that the film does not glorify violence, but instead shows the consequences of it.  What do you think?
