Jonah Hex wasn't his or Nevildine's fault. They only wrote the original rough draft which was a hard R Crank-style insano action movie and were SUPPOSED to direct it but then WB panicked when Watchmen underperformed, booted them off and had the script re-written by a ghost writer and got a director who did nothing but animated movies. Look it up.
Also, Taylor did Happy which was one of the better SyFy shows. So feels like he was just for hire on this.
As for the budget, between this and Expendables 4, I get the feeling Millennium is embezzling money. NO WAY did Expendables 4 actually had a $100 million budget like claimed.
