One sided coverage on many issues only. Interviews are unprofessional on TV, going beyond questioning; attacking guests who often speak on traumatic experiences relating to the story the channel is covering: I witnessed instances of victim-blaming happening on screen with no shame during such interviews. Reporting of inaccurate information. Doubling down on facts that were proven false. Denying "inconvenient" information that doesn't support the narrative blatantly...
I am well aware that many networks have their own agenda, but even nowadays this level of actual audacity and unprofessionalism is rarely see, and it is insulting to every sane viewer.
