In The Air Tonight wasn't written for critics though. That song really made him a superstar nonetheless (critics are rarely in sufficient enough numbers to make or break a musician).
As far as I am concerned that song was about the mood and ambience of the song. The lyrics were ambivalent enough to allow all the folk tales to make their rounds and created an aura of danger and intrigue around the song. Which in turn made it more popular with the youth at the time.
I recall John Mellencamp addressing Jack and Diane in an interview and not shying away from the fact the song made him big. Specifically his opportunities with women.
He said to the effect (I take some liberty with the original quote based on memory) "I don't run away from Jack and Diane, because of that song I could write Hurts So Good and have fun with the ladies".
Sometimes one song just opens up so many doors for the rest of their lives, even if they are sick of singing it. Better to just embrace it even if it runs it's course. Phil is better than that one song, though it's my personal fave of his (I'm not a super fan or anything)
