I loved it, personally.
Is one of the few Remakes that I see as a separate game, I don't compare it to the original at all (not saying you shouldn't, I'm saying I don't).
But if I were to, the Original is transparently superior in every possible way.
Specially the cold atmosphere of the Original. Is not only unmatched by the Remake, but it's unmatched period.
Very few games come close to it.
But I'm only making this comparison for this thread, because outside, I don't think about it.
If I want to get a more dumb-fun version of MGS 1, I go for Twin Snakes.
If I want a more interesting-dumb version of MGS 1, I go for the Original (Not saying the OG isn't fun, by the way)
Also
Ryuhei Kitamura directed many of the game's cinematics to look identical to those in the original Metal Gear Solid, but upon inspection Hideo Kojima asked Kitamura to redo them in his well-known action style.
This very much eases off any issue I could have about the cutscenes.
Because if the choice to make them the way it was, was a decision made by anyone else (Konami, for example), I could see it as a disrespect on the OG, even if I myself enjoy them regardless (I do)
But if the creators themselves embraced that change, I have no issue with it, they matter the most when it comes to that.
Rather I like the change or not, that's another story.
And I 100% get why a lot of people didn't like it.
