Doc Savage Music Video (1975)

Is this movie as bad as everyone says that it is? It's been a long time but I remember enjoying it. I am presently making my way through the recently released volume 1 of classic DC comics reprints. They are kind of silly but a lot of fun.

I have also subscribed to the latest DC comics series but I haven't started reading it yet (I think that they are on issue two so it's not too late to jump on). Reviews on the net seem to be mostly negative for this one though.
