Embarrassing if you were cheering for Argentina :P Personally, I was a US team with Spain as my back-up. I don't think it was as embarrassing as the score suggests, if you watched the game. It didn't really get out of hand until late because they were forced to throw more forward, and defense had to suffer, and unfortunately, the Germans are a side that can capitalize of such opportunities.
I don't think Messi ever really got going to his full potential, nor has Fernando Torres. Look at it this way, you made it a lot further than most teams, and played a squad that gets better as they go, like a steamroller.
Saw it and I felt that Argentina were tactically naive and defensively frail as is often the case-they afforded the Germans too much space and it wasn't a matter of trying to get the ball because they couldn't even get close to the man to begin with. Overall, this World Cup has been absolutely pitiful and I was infruriated by how Brazil were eliminated-I'm hoping Germany do the job as they have deserved it thus far (Uruguay have looked alright; Holland are thugs, Spain have been pretty mediocre)
