KK Menon is indeed the most admirable actor in the flick. He shines in his villainous act. With contact lenses and 'boaty' dialogues he shines.
Music by composer duo Sachin-Jigar is convincing in the flick. Most of the songs are situational but won't be remembered once you leave your seat expect the ‘Bezubaan' track.
The 3D effect is beautifully gelled making you feel to be one amongst those dancers.
I'll go with 2.5 stars for ABCD. It's a treat for dance lovers while the acts and script put the flick down.
