Not a bad watch overall. Tense in moments.
Most viewers will dislike this movie because it spends around an hour showing the protagonist taking her customer service calls. And this is a fair criticism. It felt like viewers were undergoing training watching her.
I'm a bit different though. I personally enjoy looking out for layman moments in movies. So while I agree that the runtime could have been better fleshed out with actual plot points, I am not marking down the movie as much as others might based on this alone. My guess is the director either wasn't confident in his ability to make good action sequences, or he was trying to go for a slow burn psychological thriller. Either way, a more balanced use of the runtime would have been better.
My criticism stems mainly from other things. The most jarring was the horrendous sound and lighting. Couldn't make out the dialogue at times, and the fight/cat-and-mouse scenes were in parts indiscernible.
On that note, I thought the action was quite badly choreographed. Not to mention the highly implausible ending.
