I remember how depressed I was when the last season aired, during the whole season I knew what was coming - the end. It's still hard for me to watch the last season because of it. What kept me going? Hope. Hope that someday there would be something that continues the series. Film, animation, spin-off, and all of the above almost happened. And that hope never left me, I wouldn't let the show end, I kept believing like a stupid person that something would happen someday. And, well, it paid off! The comics were announced! So that took me out of the depression, the fact that the series continues. Now, I don't like the comics or this media very much, but it helps me to know that the fandom isn't dead yet.
