I’ve now watched both. I didn’t know the 2024 version was a remake, or I’d have watched that second, but I actually think that watching them in ‘reverse’ order is a better experience. If you’ve already seen both, maybe you can sympathise with that view.
Both films are excellent, don’t get me wrong. But there are subtle (and some not-so-subtle) differences that really, really make the overall experience very different, including the impressions and understandings you come away with. The newer film is almost insultingly Hollywoodised, as it waterboards you with exposition that the original has no problem risking you not figuring out on your own.
Please do yourself a favour and don’t read up on either film before watching them. I’ve been reading reviews of the newer film that completely spoil scenes in the original that were different. It’s unreal how cavalier people are with that sort of thing 😒
So, my recommendation is to watch James MacAvoy absolutely demolishing the scenery with his chompers (I mean that in the best possible way), and then grab a cuppa and a blanket and watch the original.
