I remember when TTG was first shown, and I thought it was amusing. Of course, this was back when it was just a five minute clip episode, and it was kind of like what they did in their off time.
And then this show became a real show, and I watched it for a bit. I tried. I really, really tried. But I just couldn't. They gutted Robin, BB, and Cyborg. Robin is now nothing but an obsessive control freak who whines like a baby when he doesn't get his way, and spouts nonsense like, "Your forget. The Titans are SORE LOSERS!" What a horrible lesson to teach kids. Beast Boy and Cyborg end up helping the bad guys, or being just as bad--if not worse. I mean, remember the episode where they literally destroy the future of the planet just so they can avoid being responsible? What the hell? And then there's the episode where they brought back Aqualad and some of the Young Justice characters, just to have those characters literally point out all the flaws of the show and how twisted the Teen Titans are for role models, and the show turns it into a joke.
And then I began to notice that this show seemed to be on more often than any other show. Like, other shows would completely disappear from CN's lineup for days, weeks, or in some cases even longer, but TTG was always there. And any time a show vanished, TTG would fill the slot.
So truthfully, this isn't all that surprising to me. This show has slowly been taking over the channel for a while now. I guess they just decided that it was finally time to go all out with it.
