3 Questions About the End [SPOILERS]
1) When did Ella have time to call the police? She saw the lady's photo on TV and that somehow clued her into the documentary he'd done in Buffalo... she compared the tape to the crime scene photo... then the police arrived during the confrontation. How'd that happen?
2) How'd the victim's face tip Ella off? She never saw the face in the video because the woman was concealed by shadows. Ella had analyzed the crime scene photos & missed the star tattoos and chipped nail polish on that lady's hands (blind as a bat, completely oblivious)... she never made the connection... but somehow, the face tipped her off?
3) The Award-Winning documentary was filmed in Buffalo... why would the woman in the video still be wearing the same chipped nail polish years later? I know that the star tattoos were unique and would've been a dead giveaway, but the nail polish being the same is implausible.
Hated the concluding line too... "I just thought of something else. *beep* you."
