Is 24 megapixels bad?

I'm an amateur photography that previously owned a Nikon d3000 I'm now gonna upgrade to the new d3200 but I've read and watched some reviews and they said the 24 mp was bad? I thought the more megapixels the better… I'm confused? Can you explain this to me

Few people need these extra megapixels, 10 MP is enough unless you are making very large prints

Yes, "unnecessary" is far different than "bad"

On a P&S camera, a 24 mp sensor would be horrible, too many pixels jammed into a tiny sensor. On a sensor that is over 15 times larger than a P&S camera, 24 mp may be too many for an entry level camera, but until we see how that sensor performs from tests done by Dx0 Labs, there's no way to tell.

For reference, both my D300 and D3 have 12 mp sensors.

Here are two sample shots using them at high ISO settings, the best test of a sensors performance.

D3 @ 25, 600 ISO

D300 @ 3200 ISO

It's questable that 24 MP is a good idea in an APS-C sensor. It could capture finer detail than fewer megapixels. It would also magnify any little bit of camera shake, optical deficiency, or focus error. To look good at full 24 MP resolution requires a good tripod and great lenses. The file sizes would be large. You could select medium resolution to resize to a more "sensible" resolution, and probably many D3200 owners will.
Increasing pixel density can increase noise and noise reduction artifact. Technology is improving, and pixel densities that used to look bad can be pretty good in the newer sensors. Even so, a new-and-improved 16 MP sensor probably could have less noise and better dynamic range than a new-and-improved 24 MP sensor.

Everyone else has just about said the answer, megapixels are nothing to do with good quality, 2 megapixels are considered HD, i have canon 600d and i think the results with the 18-55mm lens is great, but if you do not want the canon 6000d then these are the things you will be needing to look for in a camera,
Focusing points
modes on the camera
Iso settings
and yaddy ya ya
just study up on all of these things because these are the things that make a camera good!
hope i helped

No it's not bad. You just need a lot of hard drive space to store your shots and hard drives are cheap so it's no big deal. If you do not have a good computer you may run slowly. Check if you can shoot in various formats on the D3200 like you can on the D800.It's a great camera and you should get it.

As Jim A. Has indicated the megapixel war is over. As long as you have at least 5megapixels your are fine. I have a 5mega pixels camera that turns out beautiful 16x20 prints. Is that big enough for you? I don't understand why more mega pixels are bad, they are just useless in my opinion.
