I thought it was ridiculous actually. First off, Walt somehow managed to park his car beside the right building. How did he know which building the meeting would be in? What if they had been in the basement or upstairs? What were the chances that all these deadbeats would be standing up at the same time? There were plenty of chairs around. Why did all these people keep standing once the shots started? Shouldn't they all have hit the deck immediately instead of just standing there letting themselves get shot? How did Walt get shot when he was laying on top of Jesse under the line of fire? What would he have done if the guy he met in the parking lot wouldn't have gotten into the car with him and instead forced him to just leave it where it was and walk from there? I'm sorry sports fans, but that was about as contrived an ending as was ever concocted in the history of writing.
Now, back to your regularly scheduled programming.
