This documentary does not give the viewers the information they need to make any kind of an informed decision about Alex. In order for this film to actually be something that the viewer can watch and make up their own mind about, the viewer would need to already enter the film knowing that Alex is a liar and nothing he says can really be taken as sincere. You already need to know that there's a reason not to trust him before you watch, and that's an absurd expectation to have for most viewers who are randomly coming into this film.
