After watching that Metroid Prime LP, I am indeed pretty apprehensive about replaying Other M at all. However, GT's review made the game look like something I'd replay without question in the future. Dunno.
Just to ask, how often is Samus's body language shown in cutscenes right before or after boss battles? I not only hardly remember any such thing, but have a hard time conceiving it being done in the game at all. The one good thing Prime does for Other M is slightly justify Samus's "weak" character in the latter due to her body language in both games being similar - but then we arrive at the conclusion that Prime characterizes her better if her reactions upon seeing certain bosses aren't shown very often in Other M.
You're making too much of a big deal, in the PRime games she's just ready for Battle and does her usual battle stance. Can't read much into it because there isn't anything to read into.
