How is HM a moot point? You can go to it and there will be 20+min long waits. You go through the stretching rooms and the funnel is backed up. That's pretty much maximum throughput for the Omnimover.
Again, it's a 40+ year old ride, and the "well, it's an Omnimover so it just gobbles up people," excuse doesn't fit. For TLM or Nemo There is almost never a line. I think that the People Mover will backup before TLM will at the MK. The People Mover, while not an Omnimover, essentially acts as one with constant loading and unloading.
No matter how you slice it, TLM and Nemo just aren't compelling. I get it some of you really like those rides. I don't fault you for it. I'm just saying that you can see by the crowds that most people don't really care for them or, at least, they're not compelling enough to ride again and again.
