Tooley I Am King’s review published on Letterboxd:
What dull mess of a film. Luc Besson's direction here is just terrible. His choppy structure choices and idiotic plotting make Lucy an incoherent borefest. Seriously, this film is an insult to my intelligence. And if the dumb story weren't enough, the characters are as bland and one-dimensional as it gets. Doesn't help that ScarJo is an incredibly wooden lead.
All in all, I really disliked Lucy. Science-fiction is my favorite genre, and this film took a steaming crap all over it. Would not suggest to anyone with a measurable IQ level.
