I love NLG, I truly do. Luigi's Mansion Dark Moon was a great game.Good Lord the vitriol in this thread is ridiculous. This game looks like a super fun Metroid spinoff and Next Level Games is awesome.
But I feel like the backslash is justified. People have been clamoring for a classic Metroid game for years, and Nintendo has been shown to be really receptive to fans recently, what with stuff like adding fan-requested characters to Smash and hell, even releasing Mother stateside for the first time. But this is not only a significant departure from what people wanted, it also makes them feel like they're not being listened to. About the rest of your comment, "fun" or "bad" seems really subjective terms not suited for a game none of us has played yet - I think it looks bad but we all know how 3DS games look on high-res screens, and it might as well be fun.
But my point is, this is such a departure for a franchise for which people have a really solid grasp on what they want to see it turn into, it would be silly if NLG hadn't expected this sort of reaction.
It's as if they'd revealed the Star Fox prototype to be a small part of Star Fox Adventures 2.
