Acting:
Sara was overacting and Kartik needs to explore himself if he can do such genre because he does the same things as he did in Pyar ka Punchnama which isn't working in any of his recent movies. Kartik's acting skills were particularly pathetic when he plays role of Hooda in Flashback. Saif in original Luv Aj Kal was much better in flashback and is remembered for his role what he did in flashback. Arushi's work was commendable.
Storyline:
Was pretty much anticipated being kind of remake so nothing new.
Songs & Dialogues
This is where this film lost it completely. I couldn't remember even a single song or dialogue after I left the theatre. Saif's movie is remembered for superb songs that are still in playlists of many and some dialogues also but this movie sucks.
Total waste of money, even cheesy new couples will hate it and sorry to say but these 2 neither have any chemistry which could be visible in movie nor they look good together
