Its funny but not what you call laugh out loud funny!
I like this movie as it is quite amusing and its a great cast and the storyline is ok but its just a bit predictable and can get annoying in places as its that sort of typical movie where you've cried wolf too many times no one believes you and then everyone and everything is then getting in the way of things, so it can get irritating but apart from that its worth a watch even if you only watch it the once.
Dustin Hoffman plays a man who isnt your typical hero and is only concerned about himself but when a plane crashes down in front of him he finds himself becoming an international hero and loved by eeveryone.... the onlky problem is some hobbo has taken the claim for something Hoffman has done! so throughout this movie we find out how hoffman wins his money back and becomes the hero!!
Hero is perfect for the intelligent moviegoer who wants to watch a film for fun, and that is the context in which it should be understood. Personally I find this a very good satire, that has actually a good point. In their search for sensational, touching news, TV stations will do really everything and seem to forget that the most important thing is still reality. If you are looking for a good comedy, with some fine acting and a good story, than this movie is really something you should try.
