I agree with you Drtooth. But now I don't know where they stand. But Look at the Flintstones with there Bedrock superstar. I'm a big Hanna-Barbera fan (Who worships the two guys) and William Hanna and Joseph Barbera would not be happy if they saw "The Bedrock Superstar". They would be so upset right now. I don't know what they would say.
I'm a big H&B man too... I mean, it depends on what side of the glass you look on, but I feel the 70's was definately not their decade. They did have a large output of material, but most of it was self-copying. I think Hong Kong Phooey was their best work of that decade, even though half their output of that decade was based on fads at the time (Kung fu movies, here). They had a tough time too in the 80's, but some of that stuff was pretty creative (Fantastic Max, Don Coyote to name a few), and they did pretty good new stuff with classic characters like Yogi Bear. But I digress...
FIlmation is reguarded as one of the worst animation studios of all time, especially by former employees. I will say, I do wanna see their version of Mighty Mouse again. I did enjoy it when I was younger, and from memory it was pretty much the best of their adaptions of old cartoon shows...
Plus if you look at the animation on terrytoons' 1966 show, Mighty Heroes, thy do have the same style of reusing the same animation over and over throughout the series.
