I definitely gotta play more metroidvanias going forward. Metroid Prime is very good but I did have a lot of small grievances with it, the backtracking and the boss fights being the worst of it. When I say backtracking I'm not referring to revisiting areas, I'm talking about having to traverse the same pathways over and over again to get to and from a specific area. My problem with the boss fights comes from how long they take and how they aren't involved enough to remain interesting for the whole duration. None of my complaints are major enough to ruin the game or anything but they're enough for me to dock it a few points.
