They somehow managed to fit 3 different Alien flicks in this one movie’s 2 hour run time. The pacing is damn near perfect, the scary stuff is scary as hell, and the alient / human / android drama plays fantastically. There was only one point that I doubted where they were going (it was something that also happened in Resurrection) but the direction they went in was appropriately horrifying and worked well.
If you can see this in a premium format theater like IMAX or Dolby Digital, it’s well worth your time.
