The Discovery presents a thought-provoking premise: what if scientific proof of an afterlife led to widespread suicides? Scratch that – I said “thought-provoking”? What I really meant was, "absurd." Dr. Thomas Harbor, portrayed by Robert Redford, asserts he’s found "the undiscovered country," as Shakespeare put it. The film then states that “the number of suicides has quickly reached one million.” They say curiosity killed the cat, but even a feline possesses more sense than this movie does. It's simply not possible to view The Discovery with any seriousness because countless individuals have believed in and continue to believe in some form of afterlife, and they aren’t rushing to experience it—except for those who are clearly unstable. Furthermore, these believers disregard scientific evidence; if they didn't, they wouldn't be believers at all. Their convictions rest on faith, which is the foundation of every religion. Most religions also condemn suicide; people who end their lives do go somewhere, but it’s not a destination anyone desires to inhabit for eternity. It’s conceivable that Redford’s discovery doesn’t adhere to any established religious doctrine—however, the specifics are never clarified, so there's no way of knowing if these self-destructive individuals aren’t heading directly to hell (or something even worse). Regardless, it's clear that these suicidal people aren't very bright. Robert Redford’s presence and reputation can’t prevent Dr. Harbor from appearing like a charlatan, whose explanation for the afterlife sounds like nonsense disguised as science. The filmmakers clearly hold a negative view of the audience they hoped to attract, if they genuinely thought so many would willingly participate in something that's essentially jumping into an empty pool.
