Power Rangers is only 9 years old
 

I fail to see any logic for everyone to believe that Power Rangers is 10 years old. It premiered on August 28th, 1993. This is the year 2002. to put it simply 2002-1993 = 9.

I'll admit that I am really looking foreward to "Forever Red" but PR is nine years old.

They reacon PRWF is the tenth SEASON...

Yeah, PRWF is the tenth season and contains 10 years of Super Sentai. So even though, it was a complete 10 years.. it's the 10th Anniversary, since it makes more sense to count it by seasons anyway.

The thing is that MMPR season 3 was compacted and Zeo was shown in a year and a half basis. So it truely is the 10th Anniversary.

It's kinda like the turn of the millenium : Very much people made a big fuss about the turn of the year 1999/2000, while others thought it would actually occur with the turn of 2000/2001.
