If you watched Rajnikanth's Enthiran ( 2010) and liked what you saw, you might be a tad disappointed with the sequel. There's a lot of metal clanging and fist-punching here as well, but with half the spark in the first one. For starters, it is not an entirely fresh concept, and you know you're going to enter a world where robots are somehow going to save the world. Chitti who was banned in the last movie and was relegated to the museum is resurrected once again in 2.0, and join hands with Prof. Vaseegaran in waging a war against an evil force that is all set to ruin the balance and life force of this modern-day world ( read: annihilation of cellphones) . The premise is well-thought out, and in a time where love stories are the quickest way to grab audience attention, it is commendable that an effort has been made in this direction. There is jaw-dropping VFX to establish the actual premise ( i.e. horrors of cellphone addiction) and keep you spellbound at a stretch, both in the first half and post-interval. There is humor, and the chance to see the superstar in two diametrically opposite shades - as the subdued, somber Vaseegaran and as the witty, cocky Chitti. There is Amy Jackson, miraculously falling in love with Chitti, so that's some robot love there as well. And of course, there is Akshay Kumar's Angry Bird avatar that will blow your socks off. But these are just not enough to keep you hooked. You will like them in bits and spurts, yes, but you will roll your eyes at the inane writing, consistent lack of logic and a carelessness with using scientific terms, inadvertently insulting the audience's intelligence. At one point, it even feels like those biology lessons from way back in school. Crib factor - There is TOO MUCH METAL thudding and clanging, too many mobile towers and buildings getting destroyed, and just too much happening in the action sequences ( and these are one too many) , for you to follow the trajectory of the film and ultimately derive sense out of. Going mild on Chitti's superpowers may have been the smart thing to do, but well it seems the director did not want to leave even one war element out of the minefield - ultimately, making a khichdi out of it. Then there is the length - what could have been shown in 2 hours, takes an extra 30 minutes of head space for you to process, and even then, what remains is the taste of a lot of uncomfortable metal in your mouth. The last sequence will be an overdose of VFX and action-packed together, but this is also what helps the movie raise a benchmark other super hero may have to outdo, to amount to anything. This is where you feel the actual force of Rajnikanth's larger-than-life persona and realize why he leaves so many of us in admiration. There is exceptional imagination ( albeit, silly and sans logic, thereby puncturing the actual essence of the fight) as the two stars - Rajnikanth and Akshay Kumar fight it out in an epic style. The sheer scale of this climax will surely stay in your mind. All in all, no marks for the writing and points deducted for the weak character graphs as well. Both Rajnikanth and Akshay have actually delivered their best in the film, but a weak script can puncture the best of performances. Which is why this is a movie you should watch only if you don't know what desi superhero flicks CAN look like, or if you're a Rajni fan or if you want to see for yourself what cellphone obsession is doing to your brain - just maybe ALL of them.
