The crimes committed by this episode have been enumerated by many, but they mostly lose sight of one of its worst: it’s a crummy episode. Poorly written, with a forgettable technobabble problem to keep the plot moving that’s mediocre even by TNG’s incredibly low standards of forgettable technobabble problems to keep the plot moving, and a complete failure as a guest character, it’s just bad.
Ultimately, this episode reminds me of a famous exchange between Oscar Wilde and one Mr. Carson, who asked, “May I take it that you think The Priest and the Acolyte was not immoral?” to which Wilde replied, “It was worse: it was badly written.”
