First of all, my biggest gripe with this movie is that it had so much potential to be great. I was going into it picturing masterfully choreographed fight scenes, and excellent scenes of tension. What I got just, wasn't that. The "One Take" thing felt more like a gimmick and there wasn't anything that struck out to me as amazing. The script was pretty bad and the weak plot kind of stuck out like a sore thumb. Also the music got in the way at times, which took away from the tension. I would've liked no music for those scenes to really amp up the tension. But i thought there were some good things too. The set design is great, there are some cool visuals, the acting is pretty good, and despite not having amazing action, there were some pretty cool scenes. But overall, it's not what people are making it out to be.
