In what order should I play the Metroid games?

Fusion is unavoidable and the worst offender of this, so play it last. For Samus Returns, it's another thing where I really don't trust the producer Sakamoto to just leave that game alone and try to preserve it, so you're likely better off playing the original. 

Yeah between Sakamoto's involvement and Mercury Stream developing, I suspect Samus Returns will turn out rather bad.

Thankfully, as its just a remake, it can be skipped in favour of the original.
