ocelot rules, he’s the best character
That said, he’s also emblematic of the worst aspects of the series as a whole, the first of which is the one that is most often brought up in debates about its quality. Namely, the insanely complex plot. The story of the majority of the quadrilogy (1, 3, and 4) is choked with betrayals, switchbacks, secret plans, betrayals of betrayals, betrayals that aren’t really betrayals but appear to be them in every way, and oh god it’s incomprehensible. The problem’s only exacerbated by the below-average writing of the series, making the already confusing setup even less interpretable. Revolver Ocelot (above), is notorious for setting the majority of the game’s plotline into motion, and by the end of the game you end up with such a mess that Konami actually had to ship a supplemental disc explaining how everything fit together.
The second problem, related to the aforementioned bad writing, is that the game can’t decide whether it’s being serious or not. Sure, Ocelot’s a master plotter with a grudge against the game’s Illuminati stand-in, the Patriots, but he’s also a gunslinging cowboy. Who is also Russian. The game can’t decide whether it wants to be a B-movie or not, which poses a serious problem when it decides to try and push a message. It’s hard to take Kojima’s hamfisted commentary on the virtual age and the proliferation of PMCs seriously when Ocelot’s just finished telling you that if you cheat in this section he’ll know (he doesn’t know, by the way). So you end up with something that’s too preachy to be entertaining, but too goofy to carry an actual message.
god damn MGS4 was a mess
