I like it. The animation is superb (allthough the players are a bit small) and you can play the regular button-way or the Mario basketball way with the stylus. It took a while before I got the hang of that control method, but still I think it's a fun way of playing the game.
I didn't play it for more than fifteen minutes so I don't know all the ins and outs.
Backlight can be one giant light panel with a diffusor, but recently there's mini/micro LED backlighting, where you can control the light level for smaller areas of the screen, to get better contrast and color range.
