Good entertainment with some sense of humor exploring the contradictions of living on earth especially in India from the eyes of an alien. With good plot, tight script writing, good screenplay played by excellent stars.
To make it an excellent movie.
1.) more work should have been done on Alien’s feature, other Planets specification, spaceship and on technology. Should have some detailed content and some graphics on this.
2.) As movie moves the focus comes on religion only.
3.) In climax the argument ends up only on an incident, which could have an healthy debate.
4.)Why and how the train blast happen, is difficult to swallow
5.) Background music and cinematography is just ok.
6.) Songs are not very impressive.
Far away from Lagaan 3 Idiot or Taare zameen par.
