I thought it sounded interesting when I first read about it. Then I saw it. It's like Lovecraft funny. Like "human language is inadequate to describe the horror blah blah" funny.
It's like every action/adventure show EVER packed into a half hour, but the most obvious comparisons would have to be "X-files" and "Knight Rider." (Heat Vision is KITT) The only thing I didn't like was Owen Wilson's flat reading of Heat Vision's lines. And even that wasn't bad the whole time.
So why didn't it make it on TV? It's a half-hour live-action comedy without a laugh track. How many of those have EVER made it? (Apparantly people need to be told when it's funny.)
