Director Zack Snyder's movie establishes a new continuity away from the first four Superman films and Bryan Singer's Superman Returns.
Ilya Salkind produced the original Superman film with his father Alexander Salkind and family friend Pierre Spengler.
Salkind was asked to share his thoughts on the box office blockbuster Man of Steel while out in Los Angeles over the weekend.
"It's okay," he initially replied to TMZ.
Salkind was then prompted to speak more candidly by a member of his entourage, who said that the producer actually felt that Man of Steel was "too dark".
"I think it's a little Batman-ish," Salkind then declared.
Salkind's Superman films were largely lighter in tone than Man of Steel, with the third instalment even featuring comedian Richard Pryor in a prominent role.
Man of Steel director Snyder has announced that his movie's sequel will in fact feature Superman and Batman together for the first time on the big screen.
It has been reported that Man of Steel's sequel will likely be filmed in Toronto in early 2014.
That film is expected to ultimately lead to a Justice League feature. Snyder's Batman/Superman movie will be released in cinemas in 2015.
