Based on true events, Mosagallu follows the story of twins, a brother and a sister, who are involved in the largest scam in the IT Sector. The story definitely is well written and has a lot of potential to provide several nail biting moments. Sadly, the screenplay lacks execution and is a big letdown. While the first half is fast paced and has a few well written moments, the screenplay literally nosedives in the second hour. Instead of focussing on the scams which take place(the scam is just about scratched on the surface in the first hour), the second hour focusses on the brother sister relationship and the issues which they have between themselves. Also, there is an unnecessary love track that just lacks conviction. And another blunder that the makers do is dubbing Telugu dialogues on foreigners. I mean the scam as on them and hence they shpuld have retained their original voices. This for me was a ridiculous decision! The second hour faintly manages to impress towards the end but it is too little too late. The screenplay lacks the excitement and bite!
