So I'm finally watching the copy of Invasion I bought a few weeks ago, and dang, I had forgotten how good this series was!

I was trying to think about what caused the demise of this show. 

First off, its not humorous.  You don't even get a few moments of humor like you have in Lost with Hurley.

Second, the show was delayed due to hurricane Katrina, possibly causing everyone to lose interest by the time it was finally produced.

Third, its sci-fi.

Obviously it being sci-fi partially lead to the death of the show.  but I think hurrican Katrina helped hammer in the nails to this coffin.  Granted, surface and threshold didn't survive either, despite Surface being of excellent quality and Threshold being absolutely fantastic!.  But Threshold at least still has a bit of a chance via sci-fi (they are showing season 1 on sci-fi!).

Its really unfortunate, but due to the way the schows are produced, 5-6 million viewers just isn't enough.  I sure wish that someone would come up with an idea where we sell the shows to the public.  Basically a website is put up and everyone prepays for that season's DVDs.  If enough buy them, then the show is made, otherwise it isn't, or they try to sell it more conventionaly.  With this  type of scenario, they could then go ahead and sell the show to television studios and make the extra profit they want (need?) to, but do it from a position of comfort knowing that their minimum goal was already met.
