Really an amazing movie...despite the mixed reviews. I personally found this movie average when I watched it in the movies. But after watching it a third time I am amazed. This movie can only be fully appreciated if you understand the director's intentions and it mostly. I fully understand the director's intentions and thoroughly enjoyed it. But yes there are a couple of nuances, the first being the entry to nila the robot. Shankar could have done some cool entrance of the assembly of nila like with part 1 with chitti. But in the process make it seem as though dr vasegran is constructing chitti and is reminiscing the past. I also believe Shankar should have kept the two comedians for an improved entry. But instead of them hating the Nila robot they like it. Much like in part 1 where chitti kicks them in this part they could make it seem as though the robot pats them or hugs them during the assembly process.
Second I believe the song should not have been in the very end it should have been when chitti mentions Nila on the stage.
Overall this movie gave me an amazing experience and delivered on my nostalgic value.
