This movie was EVERYTHING a Psych fan could hope for in a reunion movie!
After two prior flicks that (IMO) just didn't capture the feel of the show, this one nailed it. The characters acted like themselves, the dialogue matched them perfectly and the humor and the story ticked all the boxes.
In a perfect universe, they crank one of these out every two years for the next thirty years.
(note: we watched this last July I think; I just now got around to giving it the props it deserves!)
