chemistry -physics ka locha!!!

I have been reading a few posts about chemistry between geet and vikram(what chemistry??*scratches head*%#?) and things like dd and gc are such great actors and so beautiful that they can create chemistry with any tom,dick& harry and so on. I was wondering if that was the case then why do we have few legendary couples in hollywood and bollywood. iska matlab to koi bhi khubsurat actor kisi ke saath bhi chemistry bana sakta hai. take srk for instance he has worked with great number of hot heroines but he has always looked best with kajol. how come?? abhi-ash are such a beautiful real life couple but have zero chemistry. why?? "CHEMISTRY" banayi nahi jati hai boss woh bas ya to hoti hai ya nahi hoti hai. no matter how gorgeous one looks or how hard one tries they cannot create chemistry if its not there.Hope i am making sense...

😆.. dont worry .. most of us , dont actually mean 'chemistry' chemistry.. what we mean is that since he came there is some much needed spice back in the show.. hes stirred things up..
