Just watch the original. It's older, but it doesn't take away from it.
The amount of remakes is ridiculously high, and I need to be clear... No, movies don't need remakes to be modern-day or modernized for your viewing. No it doesn't matter it's not 1080p or 4k, and the visuals are dated.. No.
And to be fucking honest, I blame George Lucas and his 30 versions of the original star war trilogy for this. Made some folks believe you should keep fucking with movies decades later to give it more character, but it's just cgi bs for 30 seconds.
But also, we don't need remakes of blazing saddles, or airplane! Or die hard, or most great movies... You just need to watch them and remember when they were released. Look up the history of what was common then. Don't just view it from your time lense, view it from the history in which is was made.
Best example of this that stands time well, Mash.. The movie and the show. Because I think it's the best example of how to turn something good into something, more. You don't remake it, you turn it into a show and build it out for long term. There are other avenues.
Just, remakes are often crap.. And they don't do justice to the originals. Stop thinking it needs to cater to you. It's a movie, it has a story. Try to absorb it. Idk.
