Christopher Nolan has a good reputation of giving movies with out-of-the-box plots and always amazing a wide range of movie lovers keeping in mind the addictivity and the commericiality in his stories. I can easily say inception is one of those creative stories he has presented to us. My humble advise - try to go to the theatre as early as possible because you would not want to miss a single scene.
The entire movie is electrifying in its own way. The subject that Nolan has chosen is something everyone goes through half their life - dreams. It has always been an abstract concept to man and lots of research is going on. The best thing about these fiction movies is about the "what-if" scenarios and Nolan did choose the best here.
I would not want to spoil any more of the story line here but all I can say is every penny you pay will worth it!
Out of 5 stars, I would give this movie 5 stars!
