Don't get swayed by bad reviews or very good ones

Cobb planted the idea on Mal's mind. The idea that the world they were living in wasn't real but a product of their dream, which at the time is real but would haunt their life for forever.
To bring his wife and himself back to reality, Cobb kills Mal(explaining the train track scene). However, the inception(idea planted on Mal's head) never supersedes. It remains intact on her mind resulting in Mal questioning her reality. Eventually, the fable crafted by Cobb drives her to the brink; where she can no longer extinguish between the reality or the dream. That makes her kill herself, thinking the reality in itself is a dream. Therefore, she throws herself out of the window, well, not before leaving a sucide not that frames Cobb for her murder.
Now Cobb feels the guilt: the same guilt that that motivates him to use real memories while building a dream. Well, this notion is a core of this movie, inception. It is layered with other contents needed for the movie to be recreational.
I'd very much like to touch on many other substance but unfortunately, time is of essence. One question though, those who are screaming their vocal cords out saying the movie lacks character depth or development and metaphors should use their superficial time to dive a little deeper and give movie a second or even third watch before jumping their damn guns.
Footnote:I believe that the crumbling skyscrapers towards the end of the movie symbolizes wretchedness of Mal and Cobb's life. Now, don't tell me the movies is all but the CGI fight sequence and 'Martrix' wannabe
