An alright film, some strange scenarios?

Rating: 5/10 (12 December 2014)

To be honest, throughout the duration of the movie, I was unsure of whether to continue watching or simply walk out of the theater. It was entertaining to watch, as an action movie, as long as you ignore the unrealistic 'scientific' explanations.
It is a fictional story and the lack of accuracy in terms of science could be overlooked. However, I was totally unable to ignore some scenes and situations in the movie.
There was a scene where Lucy/ScarJo walked into a high class, expensive hotel through the front entrance in a bloodied hospital gown with two large guns in both her hands. How the heckles was she allowed into the hotel without being noticed and stopped? At this point, she had not yet been able to mind control people, so I don't see how that would work.
Also, why on earth were these Korean drug lords/mafia creating a drug that would increase human intelligence and try to sell/promote it to junkies? Their initial plan was to smuggle it over to other countries so that they could introduce this new drug to the market, but I don't get why people in clubs and such would take this substance, considering the fact that it doesn't give you any type of high but instead, makes you smarter. It would make a ton more sense if their plan were to sell it to some crazy scientists or someone who actually wanted to become smarter rather than to try and push it onto junkies just looking for a high.
All that said, it was still highly entertaining to watch if you can ignore the scientific parts of it as well as some scenarios. It is not an overly lengthy movie to watch, so it wouldn't kill to catch it, but I would not encourage paying to watch it. If you are interested, watching it online would be make more sense.
