It wasn't a lava lamp. It was a tube that used a very unique method of lights and reflections that were controlled depending on the needs of the scene. It would be slow and steady in one scene, but when you want to go to warp, it'd be fast and bright. Nice touches in detail. Star Trek 09 had the freaking lava lamp of doom in the form of Red Matter, complete with a water filled tube and drifting blobs.The TMP engine room was a Big Blue Lava Lamp!
With midgets in mini spacesuits to make it look bigger!
At no point did I think "brewery". I thought "Wow this ship is HUGE!"
Oh, those engineers were kids, not midgets. It's an old school tactic that even JJ used in the new Trek movie. Plus JJ actually used a midget in his movie, so all your arguments are more in line with Trek 09 than they are with TMP!
And I could care less about how big the ship is. I would rather sacrifice the sense of scale and have a sense of perspective. Say what you want about TMP engineering room, but at least you could piece together where it fit in the context of the ship. It starts in the neck, extends down the secondary hull and than splits up at an angle into the warp engines. Not only do I get a sense of how the ship works, but I know exactly where they are inside the ship! That is more awesome than just thinking "Wow. Big ship.", cause that should go without saying.
