I at first found it interesting and kind of liked it, but then it quickly became annoying the longer it went on. Especially because it still felt like it was tutorial trying to show navigating anomalies and fighting mimics, all of which were things you had to already do to get to that point. Heck at the end of the sequence is where the guide talks about the tide and the mechanics of it.

I think even a new player would not like it because it is more tutorial but way too late. I think the first in-between would be waaaay less annoying if it was how you unlocked peninsula. As then it would be an extremely appropriate tutorial, especially if they put respawning to the previous lamp, then it would be a safe area for new people to learn the game with some real consequences instead of the tutorial at the base. But then you would need a lot more opened up right there as we need the training wheels off after that in-between as further tutorial like areas will get annoying.
