Look, I’m not here to try to get you to like Keanu Reeves or Renee Zellweger if you think those two possess less acting ability than Captain Kirk and a blowup doll (“Star Trek” episode 36: The Inflated Ego). I’m just saying that I took a lazy attitude toward “The Whole Truth” (2016) and thought I had the whole courtroom thriller plot twist figured out in the first 20 minutes. Then I had my ass handed to me (“Star Trek” episode 28: Transporter Trouble). Metaphorically, that is. The movie is good at what it’s trying to be, which ain’t much.
