It's a movie, I know, but...
I thought one of the most unbelievable parts was him getting into that girl's apartment. As a woman there is no way I would even open my door living in a city like that when I look out the peep hole and see no one (multiple times). Especially when I'm basically naked. And then to open the door all the way and walk out into the hall, again, almost nude...yeah, not happening.
This movie is mediocre at very best and flat out bad if you want to be honest but that part was pretty silly.
Dick, I am VERY disappointed.
