i watched it last night as well. I liked it. Even though some may think it's slow, this one was actually better constructed than his other movies where he deliberatly put in long, boring convos just to make the impact of the action/twist at the end of the scene higher. It started to become a gimmick.
Here the convos were perfect, not unnecessary long or boring. Good amount of twists/surprises. Kept me interested all the way to the end
