If we compare this film with Telugu one i think it lives up to it. lets compare with the budget of both films Telugu one is of 30cr.(according to Wikipedia) and the Bengali one is of 6cr.(according to Wikipedia) so it shows that the film does live up to the hype and their is no problem in remake but you get to see some footage too. so in my opinion see the film as new comer not as already seen comer. & BTW. only bengali films making remakes that is not true look at the Bollywood. they also making the same thing with some improvisation. so its not a big deal.
