Is Gridlock good?

There is a not insignificant literature  arguing that our Madisonian system of government intentionally made legislation hard to pass, and that Gridlock is the ultimate protection for minorities.  Justice Scalia recently made this point in testimony before the Senate. 

Is there line between the normal grind of our legislative process (where a unified minority can delay or stop legislation it opposes) and a dysfunctional system inhibiting the country from addressing its longterm problems, no matter what party is in power, who the president may be, or how many seats the majority controls?  Or does it all depend on the eye of the beholder -- gridlock is good if you are in the minority, but it is dysfunction if you are in the majority.
