How to handle a boring campaign (as a player)

I’ve been tabletop-ing with a longtime group of friends (Shadowrun, but it doesn’t really matter). I’ve been having fun, I suppose, but we are five sessions in and there is still no semblance of a plot. There is no immediate danger to the party, no reason for us to work together and no huge reward in store. Every time the GM creates an interesting plot point (that one time we accidentally assassinated a politician’s daughter), it just ends up getting dropped and nothing ever comes of it (turns out we were never identified).

I don’t think he’s a bad GM. I just think he’s not putting any effort into creating an engaging world for us to inflict ourselves on. Nothing we do has any real impact on our situation and when someone acts like an idiot (like getting plastered before meeting Mr Johnson), there are never any consequences.

I don’t want to be a jerk to the GM since he is a good friend, but something’s got to change. Have you had to deal with a problem like this before? Is it worth it to complain to the GM, or would you try to do something in-character to force his hand?

tl;dr GM is unimaginative and boring. How do fix without whining?
