Aaja Nachle is nothing special, but I wouldn't say that it's a waste of time to watch. Essentially, it's kinda like RDB meets Swades, except with a woman as the NRI who returns to India, and a much, much, much lighter story. You can read the plot summary elsewhere, so I'll just focus on other stuff: The film has some fun music, a few funny scenes, great dance sequences (duh!), and is generally well paced and entertaining. I would have liked to see more of Akshaye Khanna's character, though. The film's problem is mostly that it's really thin on plot, and does not take much time to develop the characters.
Overall, this film is nothing amazing, but it's a fun entertainer.
