Lucy (2014)

This is a big, professionally-made movie that's based around the idea that humans only use 10% of their brains. Except that's a dumb myth from the 1800s and makes the movie impossible to enjoy.

What's even more frustrating is that there's a lot of craftmanship and talent here and, with a bit of a rewrite, it probably could have been one of the great science fiction films of all time, instead of a cringefest. If only one of the hundreds of people who worked on this had pointed out the error, at any point during the film's making...

This is also at least the third movie where Scarlett Johansson has ascended to a higher plane of reality, and I'd be curious to know why producers and Johansson herself think of her that way.
