Some commentators have criticized Goswami for his style of TV panel discussion. Kavita Krishnan, a Communist Party of India (Marxist–Leninist) (CPI-ML) affiliated activist, criticized Goswami's stance on sensitive issues and stated that "When channels and newspapers brand terror accused as "terrorists", or rape-accused as "rapists" and orchestrate the chant for the death penalty for them; when they act as stenos or loudspeakers for the police or investigative agencies in terror cases; are they not doing grievous harm and endangering people's lives and safety? Are they not conveying allegations as guilt?" Caravan magazine editor Hartosh Singh Bal referred to Arnab Goswami's anchoring as "scripted drama and he's often happy to a play a role."
Bennett, Coleman & Co Ltd, also known as The Times Group, has filed a criminal complaint against Arnab Goswami, the former editor-in-chief of the group's Times Now.

Goswami's heated discussions during The Newshour has invited criticism from newsweekly Outlook running a cover story titled 'The Man Who Killed TV News'. "Newshour is where Arnab plays judge, the audience the jury", the report stated, adding that "On key news events, Arnab has emerged as The Great Polariser, his acid tongue stripping complex issues of all nuance" Goswami, in a key note address to Goafest, defended his brand of journalism by stating, "The journalism I follow is journalism of opinion and is not PR driven. If my opinion helps bringing about a change, I will opine and not shy behind the wall of neutrality."
During the launch of the Republic TV, Goswami has said that "being a nationalist is a prerequisite to being a journalist". His ideology in that statement was criticised by some commentators for not complying with journalistic code of ethics and principles, particularly by not 'being a "watchdog" in a democracy', and also by being pro-government and anti-opposition.
