I thought it was a mildly good film; certainly not the greatest, though.  Certain images still stick in my mind, like the scene where Andrei encounters the "pagan" girl frolicking with her friends by the river, and she questions his stony morality.  I may watch it again in another 10 years or so, but I can't say I want to watch 3 hour films every week.  There's certainly something to be said for conciseness...
