That's true, tbh.
Any film I have high expectations of tends to disappoint. Actually, having said that, it seems to be that most films which other people rant and rave about tend to fall short of my expectations. It's not that I allow myself to be carried along on their enthusiasm, or that I only like small arthouse projects, it's just that a lot of so-called "great" films that people long are the ones which are constantly played on t.v. (from what I've experienced, on Freeview). As such, they tend to plump for style over substance.
I felt the same with Heat. They were brilliant, but not enough to save the film, in my eyes. I'm also finding, more and more, that I only really
love De Niro when he's playing one of his fortes; the gangster (i.e. Goodfellas, The Untouchables) or deranged, perhaps psychopathic (i.e. Taxi Driver, Cape Fear). That's probably an entirely unfair assessment, as I love him in films like Casino where, although the films is associated with gangsters, you'd hardly call him a gangster. It's not that his comedic attempts are starting to impeach on his legacy either, it's just that I'll always remember him in films such as The Deer Hunter, in which he plays an excellent role and the film is excellent, which makes his good performances in films that are good - but not excellent - just seem
not as good. If that makes sense.
