If you watch Koi Mil Gaya with an open mind with no expectations, it's a really good movie. It isn't made too well and has loads of glitches, but movies are made for the sake of entertainment and this entertains. There are parts where you cant stop laughing and exciting parts as well. Hrithik Roshan has acted remarkably well in this movie. Although the plot line isn't original and some parts are copied from various Hollywood movies, it is an enjoyable movie with good music (although it could have done without 'Haila Haila') and it was basically just plain fun. Worth a watch.
