Intersteller 8/10
You can't teach people Physics in 3 hours, you can try at the same time you can hope....but according to Murphy's another law "what can go wrong, would go wrong"
So, this movie is wrong choice to be accompanied with your non-science background GF/BF or normal F.They kept to technical authenticity but forgot to give it a soul and for a movie its soul is its story.
Like Inception it bets on its awe-inspiring concept and hopes people would not notice the lack of proper story.
Seriously, I understand lengthy shots of space shuttle driving could give orgasm to nerds but as a movie it makes you lose focus as in the end 'nothing is happening' on the screen!
Even after all these rants, I still have given it 8/10 because it excited me and made me ponder on the possibilities.
Verdict : I know most of our fellow geeks would go for it/already have seen. But, a word of caution for future audience : choose your movie companion carefully!
