End of the day, all critique becomes redundant when the film manages to entertain you. But it’s here that Lucy finds its Achilles’ heel. It intrigues you for a while, but then like any illusion you’re brain kicks into 10 per cent and looks through the con.

The problem with Lucy is that Besson’s suggestion that the unlocked intellect will turn us into superheroes doesn’t feel entirely credible. The science he lays out in the film and what happens to Lucy feel a little out of sync. You could perhaps still, with a pinch of CPH4, believe Lucy can control everything from gravity to another person’s musculature. However, when electric cables start shooting out of her and she travels back in time to touch digits with an ape like in Creation of Adam, it becomes difficult to take the film seriously.
