The ending was a total let-down
Technically brilliant, atmosphere palpable, character well-rounded considering his screen time. In fact, everything up until the furries appear was more than I had expected from a flash.
The "joke" ending isn't bad in itself, but there are two things wrong with it:
1) Non-sequiturs are fine but really belong in a much shorter movie
2) You have the talent to do so much more
That's my view, anyway. Agree or disagree with it as you please.
