First half of the film is entertaining and promising. Second half is adequate. The last half an hour of the film does not gel well with the rest of the film. However, the last 2 minutes of the film is heart-touching. The plus points of the film are Allu Arjun, songs picturization, technical values and comedy. On the flip side, tempo in the latter part of the second half went down. On a while, Happy is a happy film watch for its songs and comedy.
1. Hyderabadi: This song showcase the landmarks of Hyderabad coupled with riveting dances of Allu Arjun. Probably a song is shot for the first time at Buddha statue in Hussain Sagar. This song is merged into narration and shows how hero got settled in Hyderabad.
2. Happy: This song has a theme. The best thing about this song are the editing cuts by Anthony. The set was used pretty creatively to narrate the song theme with right picturization. On a whole it's a typical music video kind of song done with high quality.
3. Vassa Vassa: This is a massive mass number of Happy album. Mass steps composed by Ashok Raj rocks masses away. It is a set song and Allu Arjun shows his dancing prowess again with this song. The way director made Manoj Bajpai sing the first lyric of the song and clubbed such a mass song into narration smoothly is innovative.
4. I hate you: This song comes as the first song after the marriage. It is a very trendy song that has teasing elements. It is shot on the mean leads and their friends. It is another creative song.
5. Egire Mabbulona: This song is the best song of Happy. And its scored high in all aspects - lyrics, situation, music, melody and theme. Karunakaran canned this song with lots of dexterity. This song shows the blossoming of love between the lead pair.
6. Nee Kosam: It is another good song that is used for the separation of the couple with ample flashback scenes.
