Rewinding the video tape?
This might be a little nit-picky, but the creators keep harping on how realistic the movie is supposed to be, so...
After the cop shoots the fat lady, Angela tells Pablo to rewind the tape so she can see exactly what happened...
...I don't understand how we are able to see the tape rewinding and playing again... somehow the camera records its own tape? How can it record itself rewinding and playing? Or do I just not understand how cameras work?
(On a similar note, I really could not stand how Angela kept rewinding/fast-forwarding to perfect spots on the audio tape at the end.)
