I'm sorry, but this pretty much confirms it.
Metroid fans are some of the whiniest babies around.
Between this, "Fucking Donkey Kong" and constantly complaining about "Why isn't Retro making Prime 4?", it's just nothing but complaining and not giving anything a single chance.
It's a single damn trailer and it's a Next Level Games thing, who have shown what they can do in the past.
Give the game a chance. Come the fuck on.
People don't want spin-offs when the main series isn't continuing. Plain and simple.
It's clear that Nintendo has no idea what to do with Metroid after Other M. They obviously think we don't want their "SUPER SERIOUS" attempts at a Metroid game, despite them not even trying with that title, and now are attempting to kiddie-fy the series. After the failure that was Other M, you don't try to win fans back with something that doesn't even resemble what people want out of the series.
