That's not what anyone said. What was very clearly explained is the cutscenes, taken out of context, are not what is good about MGS or its plot. It's the total sum of the package. The way things tie into the gameplay itself, the intelligent use of the medium itself - and yes, emotional payoffs are a thing. Payoffs are an important part of almost every story, ever. They are not limited to random straw-man spanish soap operas. Payoffs are one of the many aspects that makes Citizen Kane - as you mentioned before - a very good film. Of course this concept is somehow far beyond your underdeveloped understanding.
But you know what? Fuck it. You know what this boils down to? You're some random manchild who read from numerous sources and communities that MGS is one of the greatest series in gaming. Instead of sitting down and trying the games out, you decided you'd watch a handful of random disjointed cutscenes from different games and base your judgment regarding a series of 8+ extremely different titles based off that.
For some reason that wasn't enough though. You couldn't simply cut yourself off from a decent experience. You saw more and more people celebrating it, and that bothers you. It gets to you deep down. It eats away at you that all these people thoroughly enjoy something that's inaccessible to you . Every day you see this thread getting bumped and people getting hype for what will likely be the greatest game ever made. Not just here, but on practically every meaningfully large general gaming forum on the internet - worldwide.
And that stings because you can't even wrap your head around why people enjoy it. Your mind is so addled and polluted with delusions that you're going to impress people with your 'refined video game tastes' that you can't pull your head out of your ass and just try it out for yourself - or at the very least, just leave the thread related to a game series you've already passed judgment on.
Instead you remain here and sling it out with people who have humiliated you and dumped on you for the past few hours. You've been utterly destroyed over and over yet you keep crawling back for more, like some kind of broken down whore that desperately needs the money to feed her heroine addiction.
This paints a very grim picture for you
