All3Media's Ruth Wrigley and Lime Pictures' Tony Wood said that the Channel 4 series scripted reality show had missed out the "humour" and "entertainment" that was central to TOWIE's hit formula.
"What it lacked was humour and it was shot upfront so we knew where it was going," said Wrigley.
"I think Chelsea lacks the entertainment part of the thought process," argued Wood.
ITV's Claire Zolkwer also claimed that filming in advance had ruined the marketing and social media aspects of Made In Chelsea, while TOWIE cast member Mark Wright said that viewers couldn't "relate" to the wealthier cast of Made In Chelsea.
Wood revealed that more reality soaps were "in the pipeline" for Lime Pictures, adding that Mersey Shore was a "possibility".
Meanwhile, Zolkwer said that she would prefer ITV1 to have a "bespoke series" of its own rather than letting it poach TOWIE.
"It's so part of ITV2's DNA, I'm not sure it would work on ITV1 so well. ITV2 is where it was designed for," she said.
Zolkwer said that she was said to see Amy Childs leave the show, following her move to Celebrity Big Brother, but claimed that it was neccessary for her to leave because her fame had hampered her role on the show.
"Essex is a community and a weird bastard child soap," said Zolkwer. "You need regneration, growth and change... and Amy [Childs]'s exit is part of that.
"Amy leaving is like Martine McCutcheon leaving EastEnders. It's the Achilles heel and strength of the show, people will get high profiles.
"Amy wasn't big in series two because she stopped living a real life."
