'Ala Vaikunthapurramuloo' has been a smashing, monstrous and gigantic box-office performer.  The Allu Arjun-starrer has been able to spin huge monies because of its cast, Trivikram Srinivas and his story-telling, Thaman's music and other aspects.

But three particular portions in the movie have made it a special one.  One of them is the boardroom segment in which Bunny dances his way to glory, imitating his big Tollywood contemporaries.  Without this scene, the spirits of the audience wouldn't have been lifted.  

It's a masterstroke that this is immediately followed by 'Ramuloo Ramulaa'.  Due credit to Thaman, the choreography, the placement of the song and the whole vibes of the family song.  This is more crucial to the film than 'Samajavaragamana'.

Third, the 'Sittharala Sirapadu' song-cum-dance element.  This has done sheer magic.  Had this fight been routine, it might have been difficult for the climax to be engrossing.  

These three portions hold important lessons for directors and writers.  It's difficult to repeat such things, though.
