Metropolis
This is officially the oldest movie I've ever seen (unless you count A Trip to the Moon, which is only 15 minutes long), and probably the only silent film I've ever seen in its entirety. Well, I say "entirety," but apparently there's still some missing footage even in the "Complete" Metropolis that came out in 2010. Most of the movie looks great though, which really amazed me. There's some seriously effective imagery here. I was also pleasantly surprised to find that this being a silent film wasn't a barrier to my enjoyment at all.
Metropolis was kinda the coolest shit ever to me up until the very ending. The ending kinda sucked tbh. But I really liked the overall theme it was going for, and watching this almost 100 years after it originally came out was a super interesting experience, both from a filmmaking perspective and from a writing perspective. I had no idea it was even possible to make a movie like this in 1927, technologically speaking, and it was very cool to see what ideas about class and technology were bouncing around in people's heads back then. It's incredible to see just how much they were able to pull off by getting creative with what they had at the time. Some real craftsmanship went into this.
There's a lot to appreciate about Metropolis (shout-out to Brigitte Helm's absolutely insane acting lmao), but my favorite aspect was definitely the music. I guess the music kinda HAS to be good in a movie like this, but whoever did the composing really knocked it out of the park. The score does a lot of heavy lifting when it comes to setting the tone here, and it does a fantastic job at selling each scene.
