24fps vs 48fps

finally i found 2 good examples of 24fps & 60fps videos...
http://www.48fpsmovies.com/high-frame-rate-example-videos/

the 2nd example was small and easy to understand!
what are your thoughts on 48fps?doeit enhance movie viewing or is at just an unwanted enhancement.

try out the fps yourself!

(PS:Peter Jackson's Hobbit is getting loads of negative response for its 48fps)
