In my opinion,
The first half was amazing, the story was different, the screenplay was brilliant, there was just enough comedy to keep the movie running for harsh critiqs,
I for the first half alone would rate the movie
9.7/10
The movie was well above my expectations and touched hollywood level,
everyone has a different liking
A flashback was played from the perspective of the villain, and having a house full of birdss, it hit me. Right in the feels, i actually felt for him, tho he sounded like a lunatic, i felt his pain.. i actually started to feel for a character. Gave me chills seeing his pain.
Chitti, also sees this but sees this in a more human way.(instead of "Omg kill humans", stop a few. Was his saying)
Where the second half flopped was when the main protagonist (dr. Vasi) gets pocessed and chitti couldnt do anything, this leads into 2.0, who invents 3.0(cool merchandise idea) and then fights the villain.
