Memento
This is actually so fucking brilliant. The story writing chronologically is already great and caused a lot of cool moments with the leading plot of Lennards memory. The plot twist at the end is also great.
Overall it extends its greatness because of the unchronologic way its told and my preciption of the movie was really influenced in both ways even after I watched it in the right order.
So many cool eastereggs to uncover in those backwards moments and different ways we see the characters. Acting was also spot on, atmosphere too, a watch that was mindfucking in a painful way sometimes but with a shocking result at the end that leaves me rather mindblown.
Meaning of how we choose remember things, how we create our own truth to hide reality and much more to explore in this.
Like I said just a brilliant piece of work Christopher Nolan I changed my opinion on you, you are not overrated your actually fucking smart man
