wow. You all fail at the art of cinema. definitely.
One of the reasons Breaking Bad is such a great show is because of the way they use different means to create dramatic effect. Sure, it's not the gun-toting, action-filled type of episode that you are used to, so you all say it sucked.
There are many ways to build tension in a scene. In this case, they chose to use the enclosed underground lab for the entire episode, with the same two characters. We as viewers feel tense because there's no progression whatsoever. Unsettled with the lack of action -- much like Walt is annoyed by the fly throughout the entire episode. The creators of the show have successfully created a sense of unrest within us to the point that when at the end of the episode Jesse finally gets the fly, we feel gratified in some way.And yet, it's anticlimactic because by that point Walt's out cold, which leaves us still with some sense of unrest...
The writers are brilliant, imo. Shame that it went over your heads...
