The writers weren't using their 10%

Rating: 5/10 (26 August 2014)

I don't think the writers or director of this movie were using even 10% of their brains when they made this film.
I gave it a 5/10 because it wasn't terrible, and I did enjoy parts, but the story suffered and it didn't seem well thought out.
The premise of the film is very interesting: a drug is developed that allows humans to use more of their brain and access parts of it that are unused. However, the logistics of how this premise was played out in the film made almost no sense, and therefore made the story seem too unrealistic. For example, Lucy, at 90% capacity, is able to time travel. Why could she time travel? Even if we could use our brains to our full capacity why could we time travel? This defies the laws of physics and there was no explanation given. You will constantly be thinking these types of questions during the film. Another one I had - why didn't any of the other people Lucy came in contact with try the drug? They could have helped her. It was loopholes in the plot that really drove me crazy. If they would have played the action down a little to go for a more believable story, I think it would have driven my logical brain a little less nuts.
It seems to be the way most Hollywood films go these days. Pay extra attention to the special effects and the action scenes, but leave the story leaking out flaws at every turn.
All in all the film had some cool visuals and interesting ideas but it didn't deliver what it could have because it was a little too over the top.
