Oh, where to start when people worked so hard on something and, while it's interesting, it just didn't deliver the wished-for punch? I shall go through it and perhaps at least it will be a learning experience?
1. Pacing: it started far too slow. I almost wandered off, and had I had anything better to do on a Sunday morning, I probably would have. Okay ... she flopped an audition where she had a fake gun ... and she wanted to get home. Why so long to build that premise? Too much time building the other characters in the elevator and then escaping, and then a second time under the wire in the parking garage. One prolonged escape would have been plenty.
2. Language. The Irish tough guy was a stereotype, and his language was far too foul. A swear here and there would have done the trick. Nobody talks like that, and if they do, they wouldn't have been in the parking garage of a swanky hotel to begin with.
3. WTF with the ending? Everything in this pilot points to a terrorist attack, and then all of a sudden we are thrown a demon in the last minute as a curve ball. You've got to build that post-apocalyptic Revelations stuff from the get-go, even if the demon still doesn't show until the end. A hooker in a swimming pool 45 minutes into it doesn't cut it.
4. Characters - too egregiously stereotypical. The main heroine, the cop and the escaped convict were okay, but everybody else ranged from meh to awful. It felt like somebody cut-and-paste the characters from Lost into this script, but then didn't put the pacing or good acting in to make them likeable.
5. Situations - Why didn't the cop break the windshield and get the second jack sooner? Why did the Irish guy run out carrying an entire case of liquor when a bottle would have done? Why is the rich lady so dippy, even after she realizes her house is being broken into? Why did the escaped convict go back for the woman's cell phone (that doesn't work) during a home invasion? All of these stereotypes kicked me out of the show.
Amazon obviously poured a lot of money into these sets and scenes as they looked acceptable from my (non-professional) eye, but even though the entire premises (either as a post-apocalyptic show, a terrorist attack show, a sci-fi show, or a fantasy show) is interesting, I cannot say I'd come back to watch it again without a serious rewrite. Sorry :-(
