Metroid is all about the creatures. Giant monster, small monsters, flying monster, water monsters, if it's got teeth, fangs, and wants to tear open your head and eat your brains, then Samus has probably done battle with it at some point. So for it to genuinely be Metroid, there needs to be monsters. A lot of them. A Metroid film should be a monster movie, not a superhero/adventure movie: we're talking about a borderline horror film here. The creature encounters should be horrific and terrifying, but Samus will prevail, because, well, she's Samus. The filmmakers should recruit some talented creature artists and effects wizards, and tell them to go berserk. No constraints, no restrictions. Just create the most awesome and extravagant creatures possible. Fangs, claws, tentacles, you name it. Whatever they can come up with. Samus had better get her power armour fully charged, because it looks like she's gonna be needing it.
