I'm in.
This has been done before. Videogum's "The Hunt For The Worst Movie of All Time" is one of my favorite series.
We Hate Movies is a great podcast as well for this type of stuff.
A coli one would be good though
There has to be criteria though. No movies that are intentionally bad, no children's films, a certain year range etc.
How about a "worst movie with budget in excess of $75 million" as one of the criterias.
