Movies like Inception are those smart bitches that take advantage of fooling around with people, now if you admit that you did not quite get the core of it then you end up being someone who DO NOT get the intellectual orgasm and If you say that 'you just loved it' then deep down inside somewhere it just sticked to you like a chewing gum in your hair.
It happened with me before, with matrix, with babel, with memento and there you go with Inception again.
Honestly I have enjoyed Inception much more than any other before mentioned movies, But can I proudly say that Yes, I got what it meant to be?...then the honest answer is NO.
Now the concept of idea stealing is quite wide and openly available [example Pritam, Anu Malik etc etc] but how about stealing it directly from mind? before it actually came down to reality....what's even more riveting is the concept of implanting idea in someone's head? Isn't that called MANIPULATION in other words? Something that our wamps do daily in soap operas? As if you go back in days of Ramayana...that's what Manthara did to Kaikeyi or a laundryman did to Rama...
