Yeah, the fillers are really bad. I'm not sure if the anime is coming to an end or not but the manga is still going. Although I am getting a little bored with it. The current Fullbring storyline seems like a rehash of what Visored.
For me it was Robotech. As a kid I watched American cartoons like Scooby Doo, He-Man, GI Joe. But once I saw Robotech, it was like nothing I've ever seen before. It had more of a mature theme with action, drama and romance.
