What a troll post.
If you hated it this much, you wouldn't have taken the time to beat it. And then posted about how you completed a game you hate so much, with a click-bait title no less.
The fact of the matter is you just wanted to get a rise out of people, in which case you've succeeded without fail.
My bias aside, a lot of the specifics you mentioned aren't untrue, but they did nothing to take away my enjoyment of the game.
If I'm playing devil's advocate, I'm guessing you are of the younger generation and weren't playing MGS when it first came out. In that respect, I suppose I can see how the clunkiness of the game compared to modern games could turn you off.
With that said, if you didn't think the game was stealthy enough, you were playing it wrong or on too easy a difficulty. If you didn't like the melodramatic dialog and story, that's just part of Kojima's charm. If you thought the controls clunky, well... you're right, but... "get gud?".
I hope you got what you wanted out of creating this thread in the manner you did.
