Ira Behr is the MAN! Interestingly enough, he doesn't see an exact ending just as he doesn't think world peace is perfectly attainable or that the ramifications of 9/11 will find a complete ending; life goes on. Very interesting and true to life. I really hope the show comes back, of course!

No one's interested in the awesomeness of his voice and sense of humor?

I am shocked Ira has never met any 4400 viewers. We are right here! We would have no problem meeting him.

I have a great voice and an awesome sense of humor...is he intersted in hearing me?

Ira is also probably right about the reason for the decline in ratings, but it is depressing to think people can be so stupid. Fine, so everyone knows the "big secret." So? Is that the only reason to watch a series? What about the great characters and stories?

For me, the opposite is true. I get tired and annoyed with shows that want me to chase the carrot, and wait several years for a big revelation. I prefer to see some questions answered, and new questions asked.
