Of these movies, list taken from Wikipedia, which ones would you say are the absolute worst and are there any that don't deserve to be on the list or any you would add. I'm talking about movies that stand out as the absolute worst of all time, not just something you thought was pretty bad.
I have to confess the only ones I've seen on this list are Myra Breckenridge, Howard the Duck (a veeeery long time ago) parts of Showgirls on TV and Battlefield Earth. I thought Myra Breckenridge was kind of entertaining but yeah it is a pretty bad movie quality-wise. I've heard that Plan 9 is so awful that it's actually a lot of fun to watch but I haven't seen it yet.
I think I would add Caligula to the list, it's also kind of interesting to watch in parts but really bad. Someone tried to put a porn movie together with a Roman epic and it just didn't work.
