IGN - Metroids suck. Not the games -- those rock. We're talking about those overgrown, energy-draining amoeba things. True, they might make for great plot devices and gameplay hooks, but they're pretty terrible in almost every other way imaginable. And yet, for some reason, we just can't seem to get enough of them, or of the franchise's other terrible fiends. Time and time again, the punishing enemies that inhabit the world of Metroid keep proving they have a way of getting under our proverbial Varia Suits, and somehow that just makes us want to kick their butts all that much more.
