How bad is it? Nothing happens.
Should you see it? No.
Perhaps someone could make a film about bored detachment and make it interesting, but this is not it. The driver for an escort service and two of the girls film themselves with a stolen camera. The one character that's not a dull monotonous bore is shrill. Spending time with these people is something you'd avoid in real life, so avoid it on film. Whether Keanu Reeves is acting a part or being himself in this is debatable.
