The Director's Cut of Watchmen is superb. It's smart and brilliantly filmed. There are aspects of noir, political thiller, and even horror. Like The Dark Knight or Logan it's more than just a comic book movie. It's so bold and profound that I would compare it to Blade Runner.
"The Empty Man" is a wonderful and intelligent cosmic horror film. I am honestly surprised by the amount of negative feedback. If you're a fan of Lovecraftian horror/ science fiction, then this is a must see horror film.
