I just got it from Gamefly today, and the controls are pretty damn good. It has really smooth aiming-not like a mouse at all-but the downside is, I didn't feel like I could move the camera fast enough from side to side (on advanced setting). Personally, I love the 2D Metroid exploration more, but if you liked the other 2, this one seems just like them with better control. It feels pretty badass ripping shields off of enemies.
I didn't think the fight with Meta Ridley was nearly as cool as it could have been. Anybody else feel the same way?
^Spoiler, before you get to the first planet. How do I put spoiler tags on something?
