Mountainous areas tend to have rapid flowing water. And it's not supposed to have mirror like reflections. Reflections are there, just very very subtle in more still parts. Nothing mirror-like in the remake. Also your lake comment doesn't make sense. Again, mirror like water. It's obvious original game is capable of reflections and there are reflections, they are just muted and water is dark obviously intentionally because that's what original, highly skilled artists wanted it to look like. Not this hack job in the "next gen" update.
