Raavanan parvayil Ramayanam / Raavanan is the HERO - Raman?

Watched Raavanan in my hometown last week with my parent. It was after 'Kandaen Kadhalai', I am watching a movie in my hometown. I thoroughly enjoyed it. Story was on the lines of Epic Ramayana, but there were minor differences. Will talk that at the end of the post. Story - Brief: To avenge the death of his sister [Priyamani as Soorpanaga], Veera [Raavanan] kidnaps Ragini [Sita - Wife of Dev (Raman)]. Veera is shown as the lord among tribals, but anti social in front of the Govt. During the course, Veera develops love towards Ragini because of her beauty and courage she shows before him. Ragini develops sympathy after hearing his story. After few clashes, between police and Veera, Veera lets Ragini go. Dev enroute to their hometown, accuses Ragini of infidelity and it is Veera who told so. Ragini goes to Veera and asks Veera why he told that there is a relationship between her and him, Veera tells he never told. Dev follows Ragini and finds Veera. Veera comes to know it is the trick played by Dev. Veera dies as the police force shoots him. Cinematography by Santhosh Sivan and Manigandan was extra ordinary. Camera captures the liveliness of the forest. Music and background score were awesome. Lyrics used were sophisticated yet simple. Dialogues by Suhasini were sharp at places and not upto the mark at places. Songs 'Usure poghudhey' and 'Kodu potta' were picturised good. Acting - Vikram and Aishwarya Rai [Dubbing by herself and Rohini at few places] scores, while Prithviraj tries to put his full effort, but characterisation makes his efforts weaker. Reason: Prithviraj playing Dev [Raman] is shown with shades of grey, that he follows Ragini [Sita] to find whereabouts of Veera [Raavanan]. Supporting cast like Karthik, Prabhu, Priyamani and Munna try to give justice to their roles. Film is technically sound, but lacks screenplay. Ofcourse, it doesn't remind you of a Maniratnam film at places. Climax could have been better if Ragini leaves Dev as he accuses her infidelity. Also, Raman's character wasn't good as he try to find Raavanan through his wife. The climax was there as Director wants to show Raavan as the hero rather than Ram. Differences: 1) Epic: Raavanan falls for Sita and kidnaps. Movie: Veera [Raavanan] kidnaps and falls for Ragini[Sita]. 2) Epic: Rama with the help of squirrel and Hanuman finds Raavanan and defeats him. Movie: Dev [Rama] finds Veera through Ragini. 3) Epic: Sita hates Raavanan and never develops sympathy. Movie: Ragini develops sympathy on Veera after hearing story of his sister and why he kidnapped him.
