Something struck me when I watched this movie last weekend (third viewing overall). For years, I thought the ship's design was completely asinine and served no practical purpose, unlike the corridors in Alien, which were creepy simply by virtue of being utilitarian (small, dimly lit, exposed exhaust manifolds, etc.).
But I may have an explanation. Whether Claire killed herself during or after the Event Horizon's completion, her depression likely tortured Weir throughout their relationship and thus, the ship reflects Weir's emotional pain. I think it would've been interesting for the characters to discuss this:
"Who designs a ship like this?"
"Weir says everything has a purpose."
"Do you believe him?"
"I don't know. We are talking about a guy whose wife offed herself in a bathtub."
"Yeah, I'd be surprised if we didn't see any of his demons here."
And something else, I used to think a docking mechanism would be preferable to the central corridor explosives, but the latter may be less failure-prone and more effective in propelling the foredecks away from the singularity. If so, then this adds a great ethical dimension to Weir's character; in spite of scaring the crew, he gave them the best possible chance to survive if the gravity drive malfunctioned.
Thoughts?
