I get that it's important historically, but it's completely unwatchable now for so many reasons.
Once they started drawing about thirty minutes in, I told my wife it'd be a funny gag if that's all the next three and a half hours of the movie was. It turns out it's what the next three hours of the movie was, so it loses some points for not fully committing to the bit.
I just didn't have the patience for this. If a movie is going to be four hours long, something needs to happen. At least one thing. That's all I ask for.
