hey, y'all!

I just finished season 8, and wanted some help regarding the movies. My BF used to watch the show when he was younger and says it's very nostalgic for him, so he wanted to watch the movies with me. The problem is, he only saw/remembers the first few seasons.

While he doesn't have time to go back and watch it all, he said that if he had a list of "the most important episodes to watch before the movies" he'd totally go for it.

Since I don't know what happens in the movies, and don't want to spoil it for me, I was wondering if anyone here could help out with a list of the absolute essencials. (even major stuff that happens in the show doesn't matter for this list if the movies don't adress or bild on it, like if the Yin Yang killer has nothing to do with the movies, then we could skip all that, etc.)

Thanks! ;)
