The infinite monkey theorem does state, after all that an infinite number of monkeys working an infinite number of typewriters will eventually come up with a passable Fantastic Four movie.
While the most recent movie reinvented the Fantastic Four as youngsters, along the lines of the Ultimate Fantastic Four comic book, the movie swings to the other end of the spectrum.
Instead, it will concentrate on Franklin and Valeria, the children of Reed Richards and Susan Storm.
My advice would be to let the public forget about how bad the last one was before they try for another, even if it is more fun.
