Metroid Prime has not aged a day. That is to say, Metroid Prime Remastered is just as annoying as Metroid Prime was in all the exact same places.

A complete lack of touch ups or re-works to the original in any significant manner may disappoint returning players (as it did me), but the truth is that Metroid Prime is still a contender for the best entry in the franchise, and possibly the greatest Metroidvania ever made. It shows absolute faith in the original product, and I believe that that was ultimately the right call.
