Just got back.
This movie was one of the few films that lives up to the hype i had going in. I really liked the way they didn't explain anything about the incident or it's origin or really anything. Leave it to the viewer to decide whether they think the creature was alien or native to earth. I really liked how at the end of the movie, the crowd I saw it with wasn't sure how to react. There were scattering claps, mixed with silence and whispering.
Excellent film.
Also, yes, the overture played during the credits was awesome. iTunes plzkthxbye.
Lastly, if they make some bullshit sequel to this already great film, I will be very pissed.
