If you're the kind of person that likes sciency / sci-fi movies, you will probably not like it

Rating: 1/10 (6 August 2014)

The plot line centres around a popular myth about the human brain, but fails to make it believable. Instead, the script contains about 15-20 mins of pseudo science lecturing by Morgan Freeman, which should, in theory, bolster the premise, but falls miserably as the actual supporting content is pretty ridiculous if you have any basic scientific literacy.
In terms of scenes, there are a couple of long sequences where nothing really happens. You'd be well advised to use these for your bathroom break. The same goes pretty much for the first 10- 15 mins where everyone but Lucy speaks Korean and there are no subtitles. Don't worry, nothing that critical happens.
In terms of acting, I'm not a great expert, but that film doesn't seem like the kind of thing that would pose a particular challenge for actors like Freeman and Johansson. Morgan Freeman reprised his typical (and probably clichéd) role of an authority figure. If you've seen it before, you will see it again. Johansson, on the other hand, had the more challenging task of appearing confident and unemotional, but also likable.
Overall, the plot was uninspiring and the actual writing does little to make it more bearable. There is some nice CGI and a bit of dispersed action and shooting of random people. I didn't like this film and would not recommend it, but YMMV - if you're not too bothered with the details and are looking for a relaxing action film, this may be your thing.
