I think it's pretty clear that many compromises in comic book adaptations (to either the big screen or the small screen) were made because of budget.
For example, it would have been unthinkable for Doctor Octopus to have appeared on-screen opposite Nicholas Hammond. If it had been done cheaply, it probably would have been confusing, unconvincing to the degree of being ridiculous, or some combination thereof. In the 1970's, it could have been done competently on TV, say with a completely stop motion animated figure (but always facing away from the camera so that animating and revealing the face was not a problem), alternated with shots of a live actor with immobile arms or arms out of the field of view, but that would likely have entailed expense not available for a TV show. The Amazing Spider-Man
was too expensive to stay on the air, just as it was.
