The Father? (Spoilers)
Overall I liked the movie; enjoyed what they did with a small budget. Also thought it worthwhile for them to stress that we can see things in our memories that never happened if we're sufficiently convinced of their truth.
Thought the father "setting up" his son so he'd do time & get clean was a bit of stretch, because if the son was incoherent & then amnesiac about what really happened, how could the father know the girl killed herself & that his son could be set up for it?
E.g., did the cops get to him in time to determine whether or not he'd even fired a weapon that night? Even if not, her hands would have shown plainly that she fired a weapon, thus making suicide the likely verdict.
I understand the desire to keep the cast numbers small--there is a small army of individuals in between an arrest, trial & conviction--but the writers might have clarified what the machine was supposed to do, & for whom. The authorities are represented as department of corrections, which doesn't investigate homicides. Might have made sense to call their leading an ADA, but then, again, why? The information they garner wouldn't be admissible in court; the defendant had no representation of his own present. Even if it was just for their own information, since they had rather cavalierly decided the death was a homicide, how could they just let him walk away should the test have shown it as it really happened, the first time.
Some of that's small potatoes against an otherwise entertaining & mildly thought-provoking effort.
