Definitley a must watch, excellant job thalaivar !! and Shankar but only for his CGI. Being such a die hard fan of SS I have to accept I was a little dissapointed with the screen play and the scope given for SS towards the end, being a scifi thriller and SS playing a role in it his villain chracter should have been introduced a little earlier and some boring sequences and songs could have been avoided. I dont mind to sit for 20 more mins to watch SS as a villain which you never get to see normally. Whatever said it is a milestone in Indian cinema and as thalaivar indicated its first of its kind .... so go for it.
