Hi Cheryl, Part 1 is 1 hour 50 mins long, but I'm not going to sugarcoat it... it is the hardest thing my husband and I have ever watched. I had to take several breaks to collect myself before I could keep watching. It's THAT bad. Definitely a must watch. But it is also extremely hard to watch. I hope that helps you prepare for it. One other note. How hard it hits you is probably going to be determined by your vaxx status. My husband and I did not get the vaxx, but our 2 child-bearing age daughters and their significant others did. Now, we have a huge decision to make... do we have them watch it or not? They got the first 2 doses and do not plan to get any more. They can't undo what's done. I'm afraid it will really freak them out. Anyway, that's our situation. Sorry that I can't end on a more positive note. All I can say is I wish eternal damnation in the hottest place in Hell to the monsters who did this to our world.
