In case you need a motivation to watch this movie, probably the picture above is enough. And I will not comment more on that in this post… well, that will be difficult…
Now, on the movie, the plot is interesting enough. Flaws? Probably lots of them. I did not really though on that while watching. If you know you are watching a Sci-Fi movie, let it go, and trust it. Do not try to rationalize. Of course, some inconsistencies can make a movie worst. But although some can exist on Lucy, I do not think they ruin anyhow the movie.
Also, the “National Geographic”-like interrupts are, somehow, interesting, although annoying on specific parts. Nevertheless, an 8/10@IMDB. Scalett’s fault too, right.
