No, metal does not always sound the same

I can completely agree if you say "I don't like metal". That's a bit sad - it's really broad - but fine. However, don't say it all sounds the same, because that's very wrong :) All the following are Youtube links.

This is metal. This too. And this as well. And this. And this as well, even if it's harder to place.

I'm not going to detail what's what, this isn't the point here. However, even a cursory glance should convince you those don't quite sound alike! And who knows, you might even like some of it. Enjoy!

Edit: My friend Meteotrix wrote the same kind of list. He's got different tastes, so that's another sampling. Soilwork is awesome though, you might have heard me say that before.
