After many years I saw it. Not as good as I remember, but it is still quite entertaining, the acting is still good, the music is still solid, and there are genuine emotions here and there.
the issues are in the creepiness of the concept in general, which I of course didn't notice as a kid. Not only does Salman help Akshay become someone completely different to fool Preity, but both also have a camera set up in her home, and watch her whenever they want. Hilariously inappropriate. There is also the fact that Akshay ends up with someone who looks like Priety, but he still says that he only ever loved Priety. Again, creepy.
the other problem is with the way the movie is shot. the movie uses dutch angles A LOT for some reason. it got a distracting quite early in the movie.
About the acting. Salman is okay. There is that general way he speaks and movements that irritated me, but in the emotional scenes, he is good. And he is a riot in the costumes. Akshay is good throughout, one scene where he cries in front of the mirror is very well done. Priety does good work too. Anupam Kher is constantly laughing in one of his two roles for some reason.
Overall, a pretty decent movie with high entertainment value. I wonder what happened to the director after this movie.
