This movie frequently extrapolates quantum mechanics to justify nonsensical ideas, capped by such statements like "we all create our own reality".
Sorry, folks, reality is what true for all of us, not just the credulous.
The idea that "anything's possible" doesn't hold water on closer examination: if anything's possible, contrary things are thus possible and so nothing's possible. This leads to postmodernistic nonsense, which is nothing less than an attempt to denigrate established truths so that all ideas, well-founded and stupid, are equal.
To quote sci-fi writer Philip K. Dick, who put it so well, "Reality is that which, when you stop believing in it, doesn't go away."
