Long delayed 'Ayalaan' and the plight of Sci-Fic in Kollywood!!

It is reported that the shooting of Sci-fic drama film 'Ayalaan' will be completed in 10 days. Directed by Ravi Kumar, the film features Sivakarthikeyan and Rakul in lead roles. Ayalaan might just revitalize the 'sci-fic deprived Kollywood'. That leads to the question, Why aren't there many sci-fic films in tamil? The reason could be the huge budget fo technology required and reception of those films by the audience. There are only a handful sci-fic films in tamil, of which only few very successful at the box-office. Will Ayalaan revive the sci-fic trend in Kollywood?
