I finally braved the final season, and watched the finale. Should I watch the movies?

I love watching Psych, it is a comfort show and I was afraid of watching the finale. I was worried that it would make me feel disappointed and like things were over. I was happy to see that while things changed, Shawn, Gus, and Julet were still together.

Can anyone tell me about the movies? I am hestitant to watch them, as I want to ensure that by the end that Shawn, Gus, and Juliet are all still together and happy.
