I manage to make it through a lot of movies that might, not unfairly, be described as "so boring I'd rather be at the DMV" or "so confusing I don't think even the director knew WTF was happening". I bailed on Birth of a Nation about halfway through. I can usually suffer through a historically-significant film even if I'm not really loving it (I made it through Battleship Potemkin while hardly enjoying a minute) but Birth was just too much. It wasn't the offensiveness (that can be its own kind of entertaining, in a pinch) but that it was really long, and really dull. Maybe it picked up in the back half, but I doubt I'll ever find out. I'd say the director's sort-of followup Intolerance also counts as a bit of a challenging watch for modern audiences, but I found that one way more fun.
