I think we may have our own definitions of narration. Taxi Driver does have a narrating voice-over, but is through a journal. Therefore, the story is not being told as it already happened, but as it is happening. Likewise for Dances With Wolves and the Star Trek films. The Thin Red Line is a series of poetic voice-overs of, what I believe, is deep into the soldiers' souls (I know that's dramatic, but...) and not on "what happened."

So, for good films that go with what I consider narration there's Goodfellas, A River Runs Through It, The English Patient, Legends of the Fall, The Shawshank Redemption, and more. One of the very best uses of narration is with Forrest Gump which Robert Zemeckis said he got somewhat of the inspiration from the narration in Amdeaus.
