A "heavily armored beast" has not described Samus since Super Metroid. We're talking about a character that can wall jump, use a grappling hook for momentum to propel her very far and has a special run attack that literally makes her fly.
Fly like a brick strapped to a rocket.
While Samus can move from point A to B, she originally wasn't
agile. She was pretty stiff. Yes, in Fusion they chopped off half her suit and she became a bit more limber, and Zero Mission have her a ledge climbing, but the old 2D games never depicted her as some sort of extreme action hero.
On a side note: I loved Super through Zero Mission and I want this game to be good. But,
every single game Gaf has ever told me was good has been awful! Every game I've bought based on Gaf recommendations I've regretted.
I want to go buy this game, but you people are jinxing this for me!
