I was thrilled to see Barbarian was on HBO. All I've heard is to go in as cold as you can and I managed to stay unspoiled thus far so I saw it ASAP. Really worth it and I do urge anyone with it on your "to-do" list to get it "to-done". I really liked Georgina Campbell and she's on my watch list now.
On the flip side, I saw my first Halloween as well. Not even going to bother Googling the name, whatever the last one is. Despite being in the demographic of people that you'd expect to have seen each and every Halloween, I never bothered with it. This did nothing to inspire me to remedy that.
These two movies are just polar opposites of the genre, that's the one redeeming quality of Halloween, at least I got to compare and contrast with something fresh and exciting.
