For those that don't know, the first season of "Grey's Anatomy" was originally scheduled to go beyond the nine measley episodes that were actually aired. The so-called "special" entitled "Straight to the Heart" is Episode 13 of the second season, which means it would logically be able to summarize about one full season's worth of show content (about 21 episodes). That might be OK if not for the fact that the first season was so short and separated by a summer break!
This type of clip show would more appropriately be aired just before the beginning of a season in the effort to try to attract more viewers before a season premire, not during the first half a new season.
As is the case for most "clip shows," here's how this one boils down: For the true fans of the show, this will be pretty much a total waste of your time as this is a complete recap of the series so far and nothing new is revealed. So skip it, or you may find yourself truly bored. For those new to the show who are trying to catch on to a very good series, then this is the show for you.
