The "Blue Bloods" season finales have a way of upping the ante and sending the characters off with a bang. It's only natural to leave audiences in a state of shock so that they'll come back in a few months when a new season begins. Therefore, it should come as no surprise to see that the highest-rated "Blue Bloods" Season 3 episode is the season finale, titled "This Way Out."
Out of over 350 rankings on IMDb, the episode has earned itself an impressive rating of 8.6/10. That makes it not only the highest-rated episode of the season but one of the most highly-regarded installments of the series of all time. The episode sees one of New York's finest get shot by a member of the Los Lordes neighborhood, causing the Reagans to band together to bring the street gang lord down once and for all.
Several people were so taken with the episode they left reviews on IMDb to sing its praises, such as one user who loved the "Excellent writing." Another user gave the episode a 10/10 while calling it a "Great season [finale]." It's hard to please every fan of a TV series, but this episode seems to have done a great job of getting as close as one can get.
