Tourian itself wasn't very special, it has red Metroids and 1 or 2 interesting rooms but the rest is pretty standard. Just the escape sequence is pretty long and forces you through an alternate path through Tourian. I couldn't find any way to "save the animals" as many Metroid fans would say.
Now with "commentary"! But don't expect too much of it. English isn't my main language so I'm often looking for words.
