Todd Willcox’s review published on Letterboxd :
I "liked" this film here, but it's one of the most disturbing movies I've ever seen. Stanley Kubrick -- a genius filmmaker -- follows Malcolm McDowell and his "crew" of fellow sociopaths as they wreak havoc. There is one particular scene -- if you've seen the film, you know the scene already I'm sure -- involving the crew and a man and his wife and a version of "Singin' in the Rain" that will make you cringe every time you hear that song in the future. The film deals with authoritarianism and anarchy like no other film had ever done or has ever done since. It's filled with memorable scenes, many of which are deathly frightening. See it. See it now.
