I liked this movie a fair amount but I think two things held me back from loving it.

First: too much time was wasted getting people through the space in the wall. Absolutely it would be astonishing. I might have restructured the movie so we didn't see any of Ejiofor's first visit other than him entering (and not seeing him arriving). Then I'd keep when he brings his "camera crew" entrance. And then I would dramatically shorten or cut Reinsve's entrance.

Second: I say I'd cut all of that because this movie has maybe too many ideas in it that are underexplored. Reinsve clearly has some emotional trauma from her childhood, but it's so.... sketchy. Ejiofor's "wife" only appears as her double (and as an imagined voice on the other side of his phone calls). I'd like something that establishes Ejiofor a little more as his pirate character -- does that seep into his character? That sort of stuff felt missing to me.

That said, the whole scene where they're talking in Ejiofor's "kitchen" worked pretty well for me, though. Creepy idea, that you can just... eat the people. I think if the ideas had been integrated a little better, that would have moved this movie from good to great for me.
