Samus is a good character, but the story of the Metroid series doesn't make the slightest bit of sense when you think about it.
I mean the Space Pirates have never used armored vehicles, or planes, or ships, or anything aside from infantry and spaceships. We could blow them to pieces with our current technology. Yet for some reason those Galactic Federation idiots forgot how to build any of those things. So they send useless infantry units to battle the clearly inferior aliens, fail, and then hire mercenaries out of desperation.
And it has a zombie virus that can infect machines. Floating jellyfish leeches is one thing, but I draw the line at machine-infecting zombie viruses.
Also bullets > beams.
Of course it's the gameplay that made the series. Still, this is the best HERO. Not the hero from the best series. And while Samus is a pretty good hero, her means of becoming one were retarded.
