The original Metroid kinda sucks ass and not just because its a janky NES game. At no point did interacting with the game feel good. Some of the music is iconic and pretty good, but most of the game I was just miserable. You can excuse a lot in early NES games as the medium being too young to have these problems sorted out, but I don't think you can do that with a lot of Metroid. It just feels bad.
