Aval Appadithaan Movie
Widely regarded as the best Tamil film ever made, which I agree with, Aval Appadithan is an outstanding cinematic work that continues to provoke and impress all those years later. With an unlikely cast of stars, including Kamal, Rajini and Sripriya, the film explores the life of a woman prejudiced against men (Sripriya) and how Kamal enters her life, only to be mystified by her personality. Rajini is marvellous as the chauvinistic lecherous boss.
The film is complete in every respect, be it direction, performances, screenplay, music (Ilayaraja, of course), editing, cinematography, et al. If there is one film that Tamil cinema can be proud of, it is this.
