I can only think of one word to say about this episode: Wow.
Adrian Monk finally learns who killed his wife, and we see him beat up the killer in a courtroom - a priceless scene! I'm very certain many men who lost their wives to a murderer would have done the same thing.
It was very touchiing to see, and I was amazed at the end of this concluding episode.
Monk was a very good show to watch - but, I would have liked to see Monk and Natalie talk about stepping their relationship a notch after the Trudy murder case was solved. After Monk gets better, he is clearly happy, and NOT miserable - I think that Monk and Natalie would have been such a great match. But, we do see them going to a crime scene together, so I hope they've become a couple!
All in all, this show was great to watch. I'll miss it, though. Thanks!
