Raavan

It may be a coincidence that two Hindi movies based on the two great Indian epics were released in the same month, June 2010. Raajneeti rooted in Mahabharatha and Raavan based on Ramayana. See, even the first letters of their titles are the same.

After being in production for about two years, the two versions of modern day Ramayana was released as Raavan in Hindi and Raavanan in Tamil. The twins were delivered on the same day. The only difference between the two movies is their lead actors.

Those who know the plot of Ramayana, will find nothing new in this newer version. Yes, here the hero is Raavana, instead of Rama. It should have been titled Raavanayana.
The cinematography of the movie is the most noticeable aspect. The climax fight is shot with the perfection of Hollywood standards. The performance of the lead cast is commendable. But, I gave full marks to Vikram, who has done the antagonist and protagonist roles in the two films. A.R. Rahman's music is good.

It can be given a rating of 3/5.

Bollywood from Hollywood

A lot of Bollywood movies are lifted, to say more euphemistically, inspired from the Hollywood movies. A list of such movies can be seen here. This may not be a exhaustive list, but gives you an idea, how much is original and how much is inspired.
