Everything like this is subjective, people. Giving reasons and explanations helps out a lot with these sort of lists
1. GLENGARRY GLENROSS -- Oscar-caliber performances across the board (only Pacino got a nod though) and a marvelous adaptation and expansion of Mamet's play. Did ANYONE see this movie when it played?
2. ED WOOD -- Although hailed by most critics as Tim Burton's best movie, it made only $5 million at the box office (at the time Tim Burton's only financial flop) and only Marin Landau received any notice from the awards ceremonies, depsite a powerhouse leading performance by Johnny Depp. Burton was also over-looked for his direction.
3. CONFESSIONS OF A DANGEROUS MIND -- George Clooney's directorial debut of a Charlie Kauffman screenplay tells the potentially absurd tale of Chuck Barris, the Gong Show host who sincerely claims to have been a CIA assassin the entire time. Clooney plays the story at face value and only allows the absurdity of it all as subtext. Kauffman's screenplay is both comedic and heart-breaking (like most of his works) and we see Barris as a lost soul, even when he's trying to tell his own story.
4. DARK CITY -- Long before 'The Matrix' completely dumbed down the notions of other lifeforms feeding off human energy, there was 'Dark City,' a far more sophisticated and stylish story built on a far more interesting and dynamic telling of a fundamentally similar story. The world of 'Dark City' is sparse and two-dimensional which ties into its concept perfectly and the dark decor and stylish design makes this a movie that exists in a world that only someone could imagine. Which is sort of the point of the whole thing. Real specualtive science fiction that challenges its audience to pay attention. (Only Dan Simmons 'Hyperion' novels better explore these notions of the energy of the human experience being something other beings are feeding off.)
