Recently, I watched...
Batman Returns (1992): The scene of the cats congregating around Selina Kyle after Shreck threw her out of the office window (and before she's reborn as Catwoman) is so iconic. I remember seeing that scene on television when I was a child. Danny DeVito's performance as The Penguin is also mega.
Blade Runner (1982): My eyes got heavy while watching it because all of the scenes are visually dark, which is certainly intentional. The world-building is amazing.
12 Monkeys (1995): It was interesting to watch this movie after having seen the TV series when it originally aired. The TV series is my second favorite sci-fi show, but I thought the movie was fine.
I have been watching Gen V and the second season of Loki as they are released (week by week). Both shows are amazing.
I also watched Memento this week; I appreciate the Christopher Nolan films that play around with film structure, The Prestige being a prime example. However, I'm not sure if Nolan keeps that up in his most recent films (here are my brief thoughts about Tenet).
