Both outstanding movies.
Dil Chahta Hai brought such freshness when the trend of Indian Cinema started changing with good movies in the early 00s. This film has a lot of realism and something you can relate due to its good story revolving around friendship even romance as well. Characters and dialogues were simple with good narration. Aamir, Akshaye and Saif had fab chemistry hence they were equal in this film. Their respective stories opposite the heroines were good mainly Aamir and Preity because of the way their romance and breakup was handled.
Chak De India is entertaining with its patriotic feel attached to it. For sports movie, you need to have some entertainment, humour and even good dialogues. This film happens to be an example with its good supporting cast. SRK is fab in a well-matured series role which excelled superbly. I'm not into hockey but this film is a good inspiration for youths who have an ambition.
