What was the point of Mr. Blue?

Rating: 10/10 (10 May 2005)

He has like one line at the very beginning, I don't understand what the point of him existing in the story was...It seemed like he gave nothing to the story at all and no one ever really interacted with him, just talked about how he might have died. I know Tarantino likes to keep things realistic and stuff, but it seemed like he just detracted from the main story (not really I'm just filling in space because of these stupid restrictions blah blah blah) So, yeah does anyone know why he was in there? OK what's up with this restriction I should be able to ask my question without getting penalized because it's not really long and complicated...
