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.
