When I first tasted a bunch of 2008 reds in NYC at the Paulee grand tasting in 2011 or so, I found the vintage to be very heterogeneous. Some wines were very nice but others seemed to have insufficient fruit and lacked a middle. Not surprised at what you are finding. Even the good wines I have had in recent years are getting to be mature. IMHO, while this is a good vintage, 2007 seems to be a superior vintage to 2008 overall.
