If HBO's new Nathan Fielder series THE REHEARSAL is real, it is one of the boldest, most bizarre, sociological experiments ever committed to film. Perhaps the most telling statement about the show is that I HOPE it's fake. Because if it's real, the real people in it will be furious when they see it. Unlike anything else on TV, THE REHEARSAL has become appointment television for me.Join the discussion and add your thoughts on what television series or film or documentary you're watching tonight (and I'll likely wind up reviewing it on the show), by writing a review, posting on the Watch This Tonight Facebook group, or interacting with us at watch_this_tonight on Instagram or @BenamorDan on Twitter.
