Don't get me wrong, I liked the idea of the Budweiser warp engine, but in execution both from an aesthetic standpoint and in universe "technical" standpoint it failed.
Aesthetically, there was no focal point. Nothing to look at. Nothing to identify as THE most powerful engine you've ever seen. Instead you just got a mismatch of pipes going every which way. Now, yeah, ok, In the real world an engine room is a cramped thing with an engine which probably doesnt look what you'd expect, but this isnt the real world, this is freakin' Star Trek. Its a film set 250 years into the future! I want to see glowing shit illuminating the faces of the characters for the same reason JJ wanted lens flare - it makes it look futuristic.
Secondly, from the "in universe" standpoint - The engine room was more like half the engineering hull. One hull breach and the entire engineering section is fucked. Open plan is great for your living room, not so great when your moving on a ship in the vacuum of space.
I get why it was there and it was a good stopgap solution, but that's all it is.
Now, don't get me started on the bloody spinning phasers.
Absolutely agree with you guys. The silly brewery sets completely took me out of the movie. Made absolutely no sense whatsoever. Your post sounds just like my post a few months ago comparing the Enterprise to a modern-day warship. Bottomline is that Enterprise is a warship and has to be designed to take damage and survive, even with the loss of forcefields to seal hull breaches. Which we never saw in TOS.
As for the brewery; I just saw a replay of the PBS miniseries "Carrier" which follows the USS Nimitz on it's tour to Iraq. The brewery makes about as much sense as the Nimitz's chief engineer taking cameras into the reactor space and we see a big giant glowing, spinning, floating sphere in place of it's nuclear reactor.
