The one thing that I can't figure out... Is the time lapse describe by crew when entering the shimmer. Also, the shimmer having a time distortion field really throws me in for a loop to find the purpose of it other than it being something pretty cool.
I'm really leaning towards the time distortion have no real meaning to be honest other than flying or sea bound short cut to the lighthouse would probably end in death.
Also, I heard complaints by the whole not wearing suits when they've done multiple expeditions and clearly have smartest people in the world studying it. It's safe to say that they reached a logical conclusion to that and the audience shouldn't need to be spoon fed details on that. Plus, suits wouldn't help anyways. Would of fukked with their genes just like everything else.
The film spends a lot of time telegraphing not only the headstrong motive of redemption of her infidelity on Portman's character, but also... Why you shouldn't trust anything she says or narrates. When the film takes 4 minutes to call her a liar. Which also a double move in the narrative. It refracts back to not only lying/keeping secrets to her team, but also possibly lying about her infidelity to her husband. It's kind of funny how you sometimes you want to root for this bytch... but then the film just oddly reminds you that you shouldn't like her. PERIOD. Which didn't make sense in the manner with her being in an interrogation. It's not like she would tell that dude about her dreams or her infidelity. SO, those scenes didn't fit, but ultimately had to be forced for the sake of her psychological journey through the film.
Also, something cute about the imagery of the creature mimicking her. In her confrontation in the lighthouse... it's not only film main plot point at stake, but her psychological battle. The creature being a mimic of herself is just a clever physical manifestation of her own demon simply being herself. It seems fitting her last enemy in her path to redemption was her. In the end, she watched herself die and became reborn as something new.
The next question is... How different is a creature with these two mixed breed of creatures with Oscar and Portman's character? We know Oscar is creature with human dna and Portman is the reverse... Are they really different?
