Sorry you feel that way, Skull, though I do to an extent agree with you. I actually really dislike the phrase "worst movie ever made" because it is such a subjective thing, and I don't believe that a perfect movie actually exists. However, the author's account is really enjoyable to read and gave me a lot of ideas in regards to what I consider "must-see" films.
Sorry its bugs me that there are a few people that are consider as "professional movie watchers" and whatever they say is golden and maybe there's a hint of jealousy in my words, because I do think Ebert, Siskel or Roeper (and such movie critics) are getting paid for not working. Really, how hard is it to watch a film and tell people what they think.
We are never going to find the worst movie ever... Some still believe Plan 9, others are saying Troll 2, I believe its Return of the Boogeyman (1994). Then others think the movie has to be boring (watching paint dry) with almost no entertainment value, some may say its a video project (a movie that looks and feel like a homemovie), a remake that fails (Rollerball 2002), an unnecessary remasted films (Like Greedo shooting first in Star Wars, the removal of guns in ET, the attempt in coloring the Black & White movies in the 1980's, etc.) and others might even suggest such over anticipate films that fail its fans (like Phantom Menace).
As for the perfect movie... really how can we measure this? If Star Wars 1977 is the most grossing movie ever made could it be easy to say its the perfect movie (after all it seems that everybody likes Star Wars) although we will find out that is false because not too many people are into space and action films.
Sorry I think its a wrong idea to come up with a rating scale (Directing, Production Values, Acting, etc.) and expect every movie will fit in a 100 point system. Because there are always factors that could never be figured out. (actors dont like each other, the script is changed several times, different directors in a rotation, what seemed like a good idea ends up not working [see Batman & Robin example], budget cuts, a major accident during production, movie doesnt age well or time makes it a better film, a movie pushed by producer that isnt working on the movie, etc. etc. etc.)
For example... Batman & Robin (1997) should have high points (although I would believe the author fuged the number here) Why? You have a good director Joel Schumacher (A Time to Kill/The Client) strong actors (do I need to list them), the Pruduction was 140 million... but as we all know the movie sucks rotten cheese.
