This movie is just too stupid to review so I'ma just bulletpoint a...
List of Ridiculousness:
NO ONE BOTHERS TO COMMUNICATE effectively:
...The bad guy could've just called the airport about his lost bag like she did and he'd have gotten it back without issue (instead of calling her directly pretending to be an aggressive TSA agent).
...Or when the mother is concerned that someone's been in her room and the ex-husband asks her what is she not telling him, she makes no mention what-so-ever about the luggage mix-up along with the aggressive unknown phone call inquiring about the bag in her possession.
...Or once the mother learned that the airport had already recovered the bag, she could have either gone to retrieve it again or inform the bad guy of where it was to go get it himself and leave her daughter alone.
...Or why did the bad guy even bother to kidnap the daughter and kill the dad in the first place? He could've just confronted the mother directly once he learned who she was and where she was staying. Had he done that he would've learned that first night that the bag was just downstairs at the front desk.
THE INCOMPETENT COPS who immediately dismiss the mother's story because they received a phone call from someone claiming to be her ex-husband just HOURS EARLIER...yet somehow, upon learning that her ex-husband was just murdered the NIGHT BEFORE, the cops now suspect her of murder?!
...What about the phone call they received "ONLY HOURS AGO" from the ex-husband (they now know had died the night before)? They're not suspicious of whoever that was posing as her dead ex? Or why? Not suspicious, at all, of the imposter's motives for calling ahead only to inform them not to believe anything his ex-wife will say?
'THE SCAVENGER HUNT' around town he had already prepared for her; what was the point? And when did he set that up? Didn't he just fly into town the night before like she did?
...There's $50 Million in that bag, wouldn't getting that back ASAP be his only concern? Not whether or not she arrives at some random destination at some arbitrary time (lest he kill her daughter thus ensuring he'd never get his $50 Million back). Who knows what all matter of things could happen to the bag while he has her running around town like a nut?
SO VERY CONVENIENT how she could always happen upon the secret phones hidden at these huge locations (like the Museum and an Aquarium) within a city she is a stranger to.
Ultimately... everything that happened happens only so the movie can happen to happen.
