I think it looks amazing. And as other have said, the fact that he look so… tired, haggard, haunted makes sense after what he lived through in Raccoon City. He look older and wearier. Almost traumatised – which he should be! Also goes without saying a way higher fidelity than before.
I also found his eyes kind of creepy and unsettling in RE4 which I don't know was actually intentional. I'm glad that's been changed.
Also I think they're going for a very different tone and style with the RE4 Remake. The original game is scary at the start, but it's wacky and silly and completely tonally inconsistent. I know a lot of people loved that, and the original is still there for you. But I think they're trying to lean into making RE4R a genuinely scary survival horror game like RE2R and RE3R.
That means Leon needs to be different – he is more experienced after raccoon city, but I don't think he's running from boulders, roundhouse-kicking zombies and firing RPGs at zombie soldiers. I think we're going to get a very different game here – a genuine re-imagining, far more extensively so than we even got with RE2R. I think his design and 'feel' has been changed to reflect that. I think they want Leon to be a much more grounded and human character – not a Michael Bay action hero.
I think that's really interesting too. I mean everyone loves RE4 – and I do too, have since I was like 12 and played it on the Wii. But everyone knows it's both possibly the best game in the series and the point at which the series started to totally fall apart. And Leon being an action hero badass wise-quipping, bizarrely funny 'villains', and all the other stuff were a big part of that. I think the team at Capcom see these remakes as a change to rejuvinate the entire franchise and take it in a new direction. I think RE4R has to be genuinely reimagined for it to make sense today. It wouldn't be enough to just update the graphics and controls/action; but given that the silliness of the original was half the problem going forwards in that series, it makes more sense to update that. Sorry for the ramble.
