He's just another Polack reinforcing the airheaded/meatheaded Polish stereotype. We may be meatheads but Lelek and I are still white and therefore, by default, have better taste than your kind.
Technically it's brilliant and the acting is great (nowhere near DDL's best but still and the rest also shines). So I'd say it's a worthy watch for any movie lover.
But storywise there's not much to latch on to for 90% of the film. Plus, its pace is needlessly slow. I like slow films when their building up to something special but this one didn't have a strong enough pay off.
