The holodeck is too small for some of the settings it's rendering.

What's so funny? The entire point of the lines is that it almost works as a green screen. All it does it render a setting within that room, but it shouldn't increase in size. It may give the impression that it looks bigger, like a mountain in the far distance, but it shouldn't be something that can be reached.

Yes, I was going to say just that. I nerdily read the TNG Technical Manual back in the day, and it did describe a "treadmill" that the Holodeck uses to give the impression of a much larger area. How it actually works, like any other aspect of such technology, was not really described, as I remember.

Ah, that makes sense. I always looked at the holodeck almost like it was a 3D printer and could render any image it was asked, but I just couldn't suspend the disbelief of the size of the room.

That's the way I understood it when they explained how the holodeck worked to Dr. Pulaski.

I like the explanation above where the ground is like a treadmill and doesn't actually go anywhere.

there are a few episodes where the crew has sex with the holocharacters.

Honestly, I would rather have the Holodeck just be a room that you walk into and it beams you somewhere mysterious. Kind of like a random space of nothingness. Keeping it in one small room just raises too many questions.
