Rizzoli and Isles was the breakout hit of last summer and I am glad that the show is back. This episode did not really show us what it is capable of. They had the season premiere of The Closer's last year as a lead-in, but they squandered all of that momentum by not having the explosion until 12 minutes in. Season premieres these days need fireworks, and they did have a lot of explosions in the episode, but you can't drag things out or people will lose interest.
They did really show what is special about the relationship between Rizzoli and Isles, a main part of what makes this show great. That they did well in the season premiere, but the whole storyline was a little unnoteworthy if you ask me.
