A pretty extreme opinion of a movie, that it failed in every respect. What acting was bad in GEN? To me it seemed like in TNG with McDowell acting well as usual and the Duras sisters being worse than in the series.
To continue the more general discussion, I am fairly unmusical and more of a cognitive guy so I naturally care more about ideas and themes than cinematography, music and emotional overload. Hence my appreciation for movies like GEN and dry, idea-focused moviemakers like Nolan and dislike of bombastic and emotional moviemakers like Spileberg or Abrams.
