The re-interpretation of the Infinite Corridor is one of the elements I am most happy about with season 3.
In Curse of Darkness,
as you are about to enter the corridor, Hector asks "What lies beyond this point?", Trevor replies "Do not ask. If you knew your heart might waver."
You enter the place, readying yourself for unspeakable horrors, and then...
...it's nowhere near as frightening as Trevor suggested. It's a bunch of floating platforms in an endless void. Enemies are at times slightly more powerful than what you've encountered earlier but not overwhelmingly so. The place is, at most, somewhat creepy. There is almost no lore about the Infinite Corridor, aside from it containing a seal to prevent Dracula's Castle from re-emerging.
For these reasons I have long wanted to see the Infinite Corridor expanded or re-imagined. The choice in the Netflix show to make it an access point to all(?) of time and space, including a portal to Hell, is clever and appropriate. This way they are also able to weave it in with an origin story for Saint Germain. Going by the ending of season 3, perhaps Saint Germain will eventually gain some mastery over the Infinite Corridor and become the time-travelling Saint Germain we know from the games.
There is huge potential for the Infinite Corridor being re-used in future seasons. I hope we'll learn what the deal was with that Central- South American pyramid, and the people running towards the pyramid, that Saint Germain glimpsed.
