Let's begin stating that I love Nolan and all his movies that I've seen so far, so I tried very hard to like this one. I'm not going to repeat what many other reviews already pointed out, but my critique is that the complicated time-line was not needed if not for adding complexity and reducing clarity in the plot. In every one of his movies, the use of flashbacks and non linear storytelling is somewhat related to the characters or has the effect of making a plot twist much more powerful, but in this case I think it was used only to mask an otherwise bad narrative.
