That seems a bit like saying what's the big deal, you can upscale dvd's to view on your HD TV. Why bother with 1080p when you can have 720p?
Okay okay it's more like saying why bother having a LCD tv with a fast response time.
Movies are shot on film cameras at 24 frames per second. IF you play those frames back at 24 or multiples of 24, 48,72,120 the frames can be displayed without any cadence effects.
Cadence is pretty simply like the difference between interlaced and progressive for frame rate. When a tv that only supports 60hz shows a 24hz frame it must show 60 frames a second. If you leave a blank for the this mean you can display each 24 hz frame 2x but you still have need to fill 12/60 hz.
To fill the space right now tv sets interpolate the missing temporal data from future frames to create the transition frames. Most of the time this is seamless. however it depends on the content and how much you care about seeing it. Less processing is good.
120hz tvs are the future. They can display native 24hz and 60hz making them perfect for movies and tv based media.
