Actually, I think
Extra Credits had a really good episode on it. Sakamoto might have actually had the right idea with samus, it's just that all of it translated poorly when it went into creating the game. It was handled by three different entities (Sakamoto, Tecmo, and the CG team) and telling the story through internal monologues was probably the worst way to tell the story he wanted to tell.
I mean, there's still a ton of inexcusable stuff, but it's worth mentioning that stuff gets lost in translation all the time.
