It was pretty good, but I thought the "agony of defeat" clips were a bit misplaced. I would have understood if they were placed chronologically, or at the beginning, to show the evolution of the Boston sports scene over the past 20 years, from the lows to the highs.
It didn't make much sense, though, to show the Larry Bird Celtics winning, followed by the Sox and Pats losing, followed by the Larry Bird Celtics winning again. It just didn't fit for me; it was like there was no reason whatsoever for what clips were picked, or where they were placed.
There were certainly enough enjoyable moments in the clip, though, so I'm not going to criticize *too* much. (I just tend not to enjoy watching Bill Buckner's error unless there's a reason for it, other than masochism.)
