I think you just got burnt out. I happens. Like me and Star Wars when I was like 13-14 (now I pretty much hate SW except the original 3 films and some select EU).

Me? Mine is one the wane aswell. I haven't watched any Robotech since this past August when a friend bought me the Mospeada collection for a graduation gift.

Two years ago if you came into my room I would probably be watching Robotech. Nowadays you would probably find me watching an Alias or Stargate DVD, or something in the Gundam universe.

Which doesn't mean I don't like RT anymore, it's just that currently Robotech isn't one of my strongest interests.

Interests run in cycles, and Robotech was dominating my cycle for a while, and it's taking a break, so that I don't start to dislike it. In due course, on a whim, Ill bust out the first Macross saga DVD and start over again. but who knows when that will be?...
