'What the Bleep Do We Know?' uses the experiences of Amanda (Matlin), a disillusioned and unhappy photographer, to explore the nature of the world around us. A slew of scientists and self-help gurus provide us with enlightenment on how things really are, but you ultimately end up with more questions than answers.

Beginning with the idea of reality, the commentators suggest that we are "reality creating machines", that something only exists once we create it, either mentally or physically. This theory suggests that the world around us is only part of what's there, that there are other universes and worlds in existence parallel to ours. Then they talk about the idea of endless possibility; Quantum Theory. They claim that there are endless possibilities in existence before we choose one. From there, they discuss the existence of a God figure and then the idea of being addicted to our emotions. They claim that we can exert supreme control over our lives and the world we live in if we can learn to tune in more with it all.

While some of what is said makes a great deal of sense, you'll also come away feeling sceptical and confused. Mixing science and self-help ideologies doesn't help you to believe what we're being told here. Neurology and Quantum Theory may be accepted branches of science, but their presence in what is ultimately a self-help film doesn't lend any more credibility to this discussion.

Lack of credibility is the documentary's main problem. Some very questionable theories aside, one of the commentators – a woman named JZ Knight – claims to channel the spirit of an ancient mystical teacher named Ramtha. If that doesn't make you sceptical, nothing will.

Another issue is that the film tries to cover a lot – religion, emotion, reality – while offering a view on life that seeks to connect all the strands. It's confusing to say the least.

Cynics among us will probably reject the film out of hand, but those that may be swayed by the commentators' arguments should also take it all with a hefty heaping of salt.
