And yet it's a near masterpiece compared to the cartoonish fourth movie. And the characters act in much more believable ways than in Prometheus.
I felt they tried (perhaps) too hard to write their way out of the utter dead end of the previous film.
It wasn't the casting, performances, effects, sets or cinematography that was wrong with '3'. It was the whole damned premise for the movie. Whilst the fourth film might not have been as well made, I enjoyed it much more, and it didn't make me angry.
Maybe a retcon explaining the substitution of clones in the 3rd film would be O.K., or something clever...
