I just remember being in that stupid dentist chair or whatever during Black ops. Story was alright from what I remember. Think there was one plot twist towards the end.
I remember that guy interrogating you was annoying.
To be honest, I kinda enjoyed those scenes.
I remember after playing MW, I went to Black Ops, and when I saw the protagonist tied into a chair with a mysteryous voice interrogating him... It was kind of creepy but I liked it.
