"Running down corridors and shooting stuff was a good amount of Metroid games in the past. Corridors outnumber central areas handily in any given Metroid game (except possibly Prime Hunters, arguably the least Metroid-y game)"
But those were not just flat areas before, that these appear to be.
A flashy-first game is awesome when it comes out. A great-first game is awesome forever.
