1. Cat played too prominent a role in the movie.
2. Never saw alien clearly. Sole close up shot of the mouth could have been anything, but not directly associated with that particular entity. Just quick flashes and hazy shots. Cheap AI.
3. No development of co-star’s clinginess. Why was he like that? What was his history?
4. New/unknown protagonists. Would like to have had at least one person in the movie that I knew.
