Law and Order SVU is not controversial. Game of Thrones was, for nudity, but Euphoria much more so, plus it depicts sex with teenagers that are barely of age.
Game of Thrones was also controversial because it started out well done (based on the completed books) but in the later seasons ran out of the author’s material and got dumber and dumber until it jumped WAY WAY over the shark and got most viewers upset at how dumb the last season was.
I saw something recently about how the producer of Law & Order is a huge supporter of police and the series sort of depict a whitewashed version where police always have right motivations, right actions and 95% of cases are solved and prosecuted. It was especially critical of SUV given the huge backlog of unprocessed rape kits in the US.
