The 48-year-old filmmaker insisted he isn't too upset that his DC Comics movie has been slammed by critics because he had the "best experience" he's ever had on a set, and he is only concerned about what fans think of the film.

He tweeted: "Prefiero morir de pie que vivir de rodillas - Emiliano Zapata".

He then explained: "Zapata quote is my way of saying I love the movie and believe in it. Made it for the fans. Best experience of my life (sic)."

In 'Suicide Squad', a secret government agency led by Amanda Waller (Viola Davis) recruits several imprisoned super villains to execute dangerous black ops missions on behalf of the US government.

The squad is made up of Will Smith as Deadshot, Margot Robbie as Harley Quinn, Jai Courtney as Captain Boomerang, Adewale Akinnuoye-Agbaje as Killer Croc and Jay Hernandez as El Diablo.

The cast also includes Cara Delevingne as Enchantress and Jared Leto as The Joker.

However, despite the talented cast, reviews have not been kind, with The Hollywood Reporter saying: "the film starts with promise but disengages as it loses its creative bearings" and it's a "puzzlingly confused undertaking that never becomes as cool as it thinks it is".

Vanity Fair slammed the movie as "bad" and "falling short" of what it hoped to be.

They added: "Not fun bad. Not redeemable bad. Not the kind of bad that is the unfortunate result of artists honourably striving for something ambitious and falling short."

Meanwhile, Rolling Stone criticised the filmmaker for compromising the "action" in order to give the movie a lower rating so more people could see it.

They questioned: "Who stole the soul of 'Suicide Squad'? I'd say it's Ayer's willingness to go all limp d**k and compromise his hardcore action bona fides for a PG-13 crowdpleaser that would rather ingratiate than cut deep, or even cut at all."

And, according to The Wrap, the movie is simply an "overstuffed spectacle".

Meanwhile, at the movie's world premiere in New York earlier this week, David shouted "f**k Marvel" as he introduced the film.

A fan in the audience had blurted out an anti-Marvel insult prompting him to blast DC's long-time comic book rival and big screen competitor.

However, rather than fan the flames of war between fans of the two companies, David later took to Twitter to apologise for his remark and admitted he had got "caught up in the moment" and assured everyone he respects the Marvel Cinematic Universe.

He tweeted: "Sorry about getting caught up in the moment and saying f*ck Marvel. Someone said it. I echoed. Not cool. Respect for my brother filmmakers."

Will Smith was more diplomatic about the wider superhero genre and stated what he loved most about making 'Suicide Squad' was that it is a celebration of "diversity" because of the eclectic cast and characters.

He said: "What I love about working with this group, as you see up on this stage, it's a rainbow. It's all races, creeds and colours. It's the diversity that this country is supposed to be about."
