I think the point with large hdtvs is justified somewhat. Not so much that tv is more detailed than reality, but that we are able to discern more details because of the perspective that some content is presented in. I will never in real life view an Apple larger than my head, where i might easily on a 60" tv. Small blemishes would then become quite apparent, etc. The much higher resolution of hdtv vs larger sd tvs allows for this, as a blown up image of an sd apple isn't going to show me anything i wouldn't see holding that Apple at a typical distance from my face.

As for crisp cinema, you have to take into account that cinema provides high resolution but has historically suffered from low contrast. This again has negatively affected the ability to resolve extra detail in depth when viewing films.

With hdtv, you combine the contrast benefits of sd tv with the resolution benefits of cinema, which are then combined with the perspective benefits of camera manipulation and film. It's too much for some people. And in certain scenarios provides a more intensely detailed up close and personal exexperience than would be possible on a day to day basis in real life.
