Interesting plot, poor execution

Rating: 4/10 (2 May 2020)

Lucy is a science fiction action movie directed by Luc Besson and stars Scarlett Johansson, Morgan Freeman, Amr Waked and Choi Min-Sik.
To be honest the plot of the movie is fresh and realistic but with some loopholes the movie disappoints.
The acting is good and Scarlett Johansson impresses in the role from a frightened drug mule to a super powered human being with extraordinary powers. Morgan Freeman is a legend and knows how to reprise his roles. Choi Min-Sik was marvellous in the role of a brutal drug lord. Amr Waked was also good.
The only problem was the execution and loopholes. Here are the few loopholes. Why the captors started kicking her stomach when they are aware that she is carrying a packet of drugs in her stomach, the drug is shown as very costly and vulnerable? Why did she go to a hospital to remove packet out of her stomach as in the previous scene she had removed a bullet from her body herself? If she was so keen to save the humanity by taking the possession of drugs why did she killed the patient on operation table? and why she shot an innocent taxi driver just because he can't speak English? From a brutal who is killing and shooting everyone to a humble and soft human in the end is something which was needed an explanation.
The movie would've been much better provided more attention were given on the development of a good plot rather focusing more on senseless action.
