Yeah, this episode was one of the worst so far. (Not counting the one with the little girl that smiled at the kidnapper that raped her aunt and killed her father in front of her... That one was the worst episode in 9 seasons, period.)
It was nice to hear accurate street names and references about Boston, and see maps of my fair city. Unfortunately, they hired someone that looked like they were 15 to be the "unsub", but his pregnant ex-wife looked 40 years older. Give me a break. The best part about the show was the sub-plot about Rossi and his favorite bar.
After that, IMDb requires me to write 10 lines of text for a review, which is utterly ridiculous. A.J. Cook is beautiful. Jeanne Tripplehorn is lovely, as well, though I wish we had seen more of her when she was younger. MGG is still annoying, though he is growing on me. Same with Pineapple Garcia (your latest flavor from Ben & Jerry's). Is this 10 lines, yet, IMDb? I'm not sure why I need to write so much to review an episode of a TV serial drama.
